A DISPUTE THAT COULDN'T BE RESOLVED!

I rate the service i received from Telkom's customer care. Its pathetic. My Feb installment bounced back which was an issue on my side. I made the payment on the 9th of March to rectify. They did not debit my account end of March. I called to query and could not get through. Spoke to a few agents which were not helpful. Have requested for collections to call me back or communicate with me in regards to the amount owed, I haven't had any communication from Telkom at all. They debit my account for double amount owed on the 15th of April which obviously bounced back as I did not have double the amount in my account. It wasn't even communicated that my account was going to be debited on the 15th of April. My normal debit date is set to last day of the month. My account was then suspended last night and no communication was received to say it will be suspended only received a message after the suspension was done. With all accounts if payment wasn't received they will be calling their clients NOT with Telkom because there is NO COMMUNICATION they just cut you off. Spoke to one of the managers in Telkom this morning and he says i was SUPPOSED to get a notification that this would happen. I explained I DID NOT. But he himself wasnt of help in getting this issue resolved. Now im charged fees from my bank because Telkom had debited my account for double the amount due and I did not have funds in there. If i am owing R1391 debit me for just that not R3100!!!!!!!!!!!!!!! WORST SERVICE CONSULTANTS EVER!!!!!!!!!
