(Update) This Sin City Vapor location is absolutely horrible. Because it is much closer to my house than the other location I use out in Henderson, I decided to give them another shot. Up until today, everything had been going fine with my routine visits for ejuice. Today, I came in to have them swap out a couple batteries for my Provari, that were no longer holding their charge. Keeping in mind that I bought my Provari from this specific Sin City Vapor location and was told when I purchased this that they DID in fact warranty these batteries (and had swapped them out for me when the previous batteries were no longer holding a charge) I was told today that their policy had changed and they have decided to no longer warranty them, because it wasn't cost effective. First of all, regardless of their decision to change policy, when you sell something to a customer and make a promise of service, you had better keep that promise and deliver on what you sold them. Secondly, this is just poor business. To treat a loyal customer this way, when they do in fact spend a lot of money with you, is unacceptable and the way you LOSE customers. I'm not asking for something free, not asking for a credit, I'm not even asking for something to be discounted! I'm asking and expecting that you honor something you sold to me when I purchased the Provari. I still have the original receipt showing the purchase and purchase date. As I PROMISED the guy in the store today, I'm leaving my 'negative' review to warn others of your poor business practices and will continue to write these reviews, until this is resolved. I will also be filing a complaint with the BBB, because this is unacceptable.
