UNRESOLVED BILLING ISSUE FOR CLOSE TO 2 MONTHS

I got a statement from Telkom for my contract after upgrading my data account. It showed an amount that was not supposed to be there. I logged a billing query call with Telkom on the 4th of March 2016 (Ref Number: ***5) and I asked about the turn-around time and was told that it 72 working hours. BUNCH OF LIES AS THEIR T.A.T IS PATHETIC because there was no update or feedback. At the end of March when my debit order date came they took the whole amount as per statement without having resolved my query. Luckily thanks to my FNB private banker who helped me reverse the transaction I then paid the correct amount thinking that they will deal with the issue on their side... LITTLE DID I KNOW THAT THE *********** BILLING DEPARTMENT AT TELKOM IS SO BAD THAT THEY THEN DECIDED TO DEBIT MY ACCOUNT AGAIN TODAY WITH THE AMOUNT THAT WAS REVERSED AFTER I HAVE PAID THE ACCOUNT. TO THIS DAY I HAVEN'T HAD FEEDBACK TO MY QUERY. GUESS WHAT.. UP UNTIL MY ACCOUNT QUERY IS RESOLVED AND SOMEONE GETS BACK TO ME TO CLEAR THINGS UP, I WILL CONTINUE TO RESERVE TRANSACTIONS..... I AM VERY VERY ANNOYED BY THIS!!!.
