I would use promotions to my advantage calling each time paying the amount agreed upon for a specific amount of months stating that I did not want Auto renewal would not give them my card to charge against and to please turn my service off at the end of the agreed-upon mouths. Most recently while following my same guidelines I called them up to take advantage of the new promotion 6 months for $30 and I have two lines by the way, and they stated I owed them $52?
The lady on the phone told me this was due to my subscription running out and they let it run for another month on each device and then turned my service off because I had not paid and I had no card on service! I explained that if you listen to what the last customer service rep agreed to with me there would be no auto-renewal and services would be terminated at the end of the contracted months. This customer rep said she could eliminate the $52 if I sign up for another 6 months however I would still need to call in at the end of 6 months to turn into contract if I so desired. I explained to her that is not what I wanted and she provided me some advice that I can simply set a meeting reminder on my phone to call in.
I explained absolutely not you have a robust computer system that should be able to shut my service off at the end of the six months. She stated that is not how it works and I had two options either pay the $52 and go my separate way or take the promotion for 6 months where are they would do away with the old $52.
And then told her to please have a very nice day bye bye! They just lost a potential life-long customer the end!
