poor service

IN december 2014 my account was transferred from nashua mobile to altech autopage due to the fact that the former no longer conducted business. i had a cell c ****le R80pm with a limit of 1gb per month. After Altech autopage took over all of a sudden i was being billed for numbers not on my account and not mine. So i approached them to fix the problem and 8 months later it has not been seen to despite many visits to thier branch and calls. then i approached them to give notice for this account to be cancelled and i was told that my account is arrears. To top it all off i have been getting my 1gb per month for 8 months now and every month i receive a bill for it which i will probably be expected to pay. as a result i have been waiting for 8 months for my account to be fixed so i can settle this account and move on. every time i call them i am told by the the accounts department that the account is with the technical dept.
