Sprint Sprint won't provide a credit for 4 yrs of their billing mistake Internet

   My husband and I moved from NYC to New Jersey 6 yrs ago. When we moved here, we had AT&T but had no reception so we switched over to Nextel/Sprint.

   For SIX years we've been getting bills that describe our surcharges as Government and State surcharges. Now that they changed their bill format, the Surcharges are more detailed but the problem is that they are all NYS & NYC taxes and fees even though we live in New Jersey and have lived in New Jersey for the whole time we've had Sprint.

   I called customer service and they opened a case 3 days ago. Today we heard back from them and they admit that the error was on their side. For whatever reason, they had our former NYC address as our user address and it was never updated. The rep was polite as can be and calculated the difference between the NY and NJ tax as being an overcharge of $5.75.

   The Problem is that they can only go back and give a credit for TWO of the six years that we were overcharged.  That is the equivalent of $276 that we were overcharged for at no fault of our own and we can't get back.
