No response for incorrect debit for 2 months!!!! Unacceptable

Ive been struggling with Telkom for the last 2 months with no luck and there call centre and branch staff are absolutely clueless. I took out a data contract in April. I previously had one which worked well. It was R99 for 5gigs. That ended in Feb 2018. When i got called for the latest deal which was R149 for 10Gig i gladly accepted. I gave Telkom permission to debit my account with R149 on the 20th of every month in tern they would provide me with 10GIG. 2 months ago a debit of R649 went though my account and when i queried this i was advised that there is a R500 account linked to my data so that when i go out of signal it automatically takes of the airtime. I ask the consultant to confirm that my account was capped at 10GIG per month and he confirmed so how is it possible that i go over 10GIG's? This was never part of the agreement and no one can tell me how this happened. I never gave permission to go over 10Gig and this was never part of the contract. I sent numerous emails with no luck and the only response i received so far which was on the 29th July is: Dear Customer, Your query will be attended to.Your case number is ********** 5. Telkom SOC SA and nothing since then either. This needs to be resolved as a matter of urgency. Under no circumstances will i approved for Telkom to debit anything more that R149 on the 20th of every month till the contract comes to an end and they will provide me with only 10GIGs data for that as per what i signed up more. Not 1 mg more.

I also sent and email to : ********** on the 25th July and still have not received a response - No regard for customer service
