 Phone companies like Verizon respond by removing cramming charges from a consumer's bill upon request, and will cease business with the company that crams.Verizon, at the customer's request, will put a Cramming Block on the customer's account, that prevents third parties from adding charges.All the UK mobile operators have a third-party direct-to-bill scheme (chargetomobile 'payforit') controlled by the Payforit Scheme Rules which prevent unauthorised charges.
