This review is for Delta Mechanical -- both AZ & CO. I live in CO but also dealt with the corporate office in AZ. I've tried to keep the review concise as possible...but the reality is, I could have written 10 pages on how disconnected the company is and just how little client service is to their organization.\n\nAs a third-party installer to Home Depot, Delta Mechanical was contracted to install a toilet for me and my family. I placed the order and scheduled the install one week out for an 8-10 AM delivery/install to minimize delays or issues.\n\nAt 8:30 on the day of install, I received a message from Delta Mechanical that they didn't have the necessary information to complete the scheduled install. I talked to both the installer and the corporate office to try and resolve. \n\nUpon my first call to the installer, I learned that although he might be a pro at installing toilets, he was anything but when it came to customer service skills.\n\nWhen I asked him what the problem was with the order and what he might need from me, he basically said, \""I've already moved on to my next job. Nothing I can do.\"" \n\nUnderstandable, considering the mix-up...only, he had ZERO interest or motivation to help. I asked that he call dispatch to find out what the issue was or where the disconnect occurred....to which he made it clear that he was busy and that he was already on his way to another job. WOW!...so, I was kind enough to give him a piece of my mind and how unprofessional that attitude was when facing a customer.\n\nThat's when I called the office directly to explain my frustration, having had to take off work for the original installation time and then to be told by the installer that helping me couldn't be fit on his plate at the moment.\n\nThat's when the customer service representative mentioned that she had called me \""one hour\"" prior to delivery to discuss the issue...the only problem is that she was in a different time zone, so it really was only 20 minutes before the schedule install time.\n\nSo, I quickly learned that I'm probably working with people who aren't quite ready to run a business or to handle customer service issues or problem solve. She said she would have to review the phone call order and \""get back to me\"", but offered no estimated timeframe or next steps -- one hour? one day? one week?\n\nClear to say that my frustration continued to grow. \n\nDelta Mechanical tried to blame it on Home Depot, but I sat at Home Depot when we originally placed the order and confirmed that all of the information had been given to Delta Mechanical.\n\nWhen talking to the customer service representative and eventually the Delta Mechanical Manager (George Ramos), they confirmed Delta Mechanical only looks at orders the day of installation, which makes ZERO business sense and probably a good reason as to why I'm as frustrated with them as other reviewers. \n\nI'm still baffled how an order placed 7-days in advance cannot be reviewed or confirmed prior to 20-minutes before install. SERIOUSLY!\n\nMr. Ramos' plan to fix it included me rescheduling my afternoon (already after rescheduling my morning) and to give me their \""New Client Promotional\"" rate with an added $20 off. Now, my bigger question was, \""Why am I just now hearing about this  promotional rate now that I'm an unsatisfied customer and nearly two hours after the first sign of incompetence on Delta Mechanical?\"" Rhetorical question of course.\n\nI let him know that promotional rates are for customers looking forward to doing business with Delta Mechanical, and that at the moment I was pretty dang far from that...having taken off work, rescheduled my weekend, and after spending two hours on the phone bouncing from installer to customer rep to manager while experiencing some of the most dreadful customer service ever -- without any resolution, other than $20 off their promotional rate they failed to offer upon my initial order and giving up my afternoon on top of the morning already wasted.\n\nMr. Ramos' response was, \""It sounds like I should just cancel your order.\""\n\nTalk about CUSTOMER SERVICE!\n\nI did call Home Depot back and we're in the process of making the situation better, including using another third-party installer instead of Delta Mechanical.\n\nI know I'm just one customer/voice, but I let Home Depot know that as long as Delta Mechanical is a third-party vendor, I will be taking my future purchases somewhere else.\n\nAgain, we're in the process of finding a remedy in conjunction with Home Depot, but the ONE GUARANTEE I have at the moment is that Delta Mechanical WILL NOT BE INVOLVED IN ANY WAY, thankfully!\n\nPlumbing and HVAC aren't my specialty, which is why I wanted the pros to do it...but take a lesson from me, there are a lot of companies and people who can install plumbing infrastructure the right way without leaving a soiled taste in your mouth. \n\nDo yourself a favor and go with another company that has a better overall rating that TWO STARS on Yelp...you won't regret.
