I was with AT&T for several years but they were constantly changing rules and pricing which caused me to be on the phone with them just about every other month. Finally I had enough, researched other carriers and decided on T-Mobile. On May 2,2023 we purchased 2 new phones and other pricey accessories, and within our new (Contract) plan the agreement was that I could use a credit card for autopay and receive a $10 monthly credit. It worked for all of 1 month, before they changed their agreement. Don't be fooled, the uncarrier aka T-Mobile is no different than any other carrier because, although we have a 'contract', they changed rules midstream by now ONLY allowing debit or bank draft for the autopay discount. This change was obviously in the works when we signed up, but not a word was spoken in its regard. I hate being misled and lied to. I am deeply disappointed in them because I thought they were different, sadly they are not.
