You had a bill with Alltel. It came out at the same time every month and was alwasy due 20 days later. OK. That's cool.
Now you have converted to VZW. Guess what? The bill STILL comes out on the same day your bill did when it said Alltel on it, but they give you even LONGER to pay it. They give you 25 days.
The fact that YOU neglected to realize you had not paid the bill is in no way the fault of the company. Did you just figure that since you didn't get a bill you just didn't owe anything? We all know better. A simple phone call to #BAL or *611, both commonly known numbers, would have told you your balance.
Me thinks you are just looking for something to cry about because you are unhappy that precious Alltel sold itself to VZW. You may not like VZW but guess what - they have THE best CS ratings of any Cellular Service in the nation. That says something.
