Verizon won't admit billing error

Question

Just got the phone with Verizon supervisor. Verizon made a 30 dollar error and won't give me my money back. I have had good relations for the last 2.5 years, but am going to switch phone company due to this incident.
Question: Anybody else notice a change in the way customer service operates? I pay extra money for the great service, but with getting cheated out of 30 dollars I see no reason to stay with Verizon.

Answer 1

To explain myself better .... nope, nothing straight forward such as you suggest, wish it was that simple.
To  make a long story short, after discussion of credit card used to pay a  bill Verizon said at the end that all was good and that "It was like it  never happened." This means all is in good standing and that the settled  dispute left me in good standing. You know, like nothing had happened.  Good. I felt relieved that the problem was fixed.
Fast forward a  couple of weeks. Phone service is cancelled due to lack of payment on  accounts. $30 dollar charge. Verizon said there was nothing they could  do. I talked with finance dept. and their manager. Still they could not  undo the charge, even though it was there fault for telling me two weeks  prior that all was good. They dropped the ball.
I have been with Verizon for 2.5 years now and have always paid my bills. This is the first time there was a problem.
I  have paid extra and stayed with Verizon for their customer service.  They have helped me in the past numerous times with both my Droid and  Razor phones.
But now I must look elsewhere because Verizon told me all was good and charged me $30 dollars to hook service back up.
I  know they think they are right, but after looking at my notes with the  conversations I had with them they are wrong. What makes me want to look  elsewhere (contract is up on one phone) is that they would rather not  give me my $30 and loose me as a loyal customer. Rather short sighted of  Verizon if you ask me... really poor customer service.
