Verizon Residential CUSTOMER SERVICE Internet

I requested that my package be degraded to Local and Regional only, and that all long distance services be blocked. I was assured that my request was being honored. However, because I try not to rely on just one individual, I called back and requested the same thing again, and I was informed that my request was already fulfilled. I was assured that no one make long distance calls from my residential line and that the long distance was indefinitely disabled. However, to my dismay, Verizon CSR failed to follow my request. Long distance calls were still allowed and that too after removing my long distance services -- making all of the long distance calls be billed at $17+ rates per minute!! I was told that the calls were made by using AT&T services and there is nothing I can do to avoid the bill that was due to the failure of following my request. Verizon did not freeze my long distance services despite my request.
