Incorrectly billed for 6 months, No Assistance

I took out a 5G data deal for R199pm in October, which I have been ridiculously billed for since. The consultant admitted to making an error that lead to me being charged excessively on the account. After numerous visits to the Rosebank store, emails between the consultant and the billing department, as well as an escalation to the manager, ABSOLUTELY NOTHING has been done. The following payments have been debited so far.<br> Oct 2014: R2 243.16<br> Nov 2014: R1 274.00<br> Dec 2014: R875.00<br> Jan 2015: R905.00<br> Feb 2015: R6 341.00 !!!<br> Mar 2015: R905.00<br> <br> A total of R11 743.16 for 30G worth of data?!?!?!? I reversed the R6k payment and now have to reverse the latest debit.<br> All I want is for this account to be closed and to be refunded what is due to me.<br> I am extremely disappointed as I have enjoyed Telkom's service for many years but I have run out of patience with this kind of treatment and using this as a last resort before lodging a complaint with ICASA.<br>
