Bad experience

Recently I got a call from Telkom to upgrade my package that included any network minutes. Only to find out the upgrade has been done on the wrong account. I call the 081180 number to get it fix however they told me about 72hrs turn around time which I didn't have, and they sent me the following sms to resolve the case. "Telkom SA: Dear Customer, Your query will be attended to.Your case number is ***0 Please do not reply to this SMS."

I then went to the branch at mall of the south to get assisted in opening another line for the unlimited of which I did.

Yesterday the 13th May I got the sms saying my line has been suspended and I have used up all my credit limit. When I called them they told me I owe them R23000 for early termination of contract. I was so puzzled as all the packages I took were on month to month and now they've closed my unlimited data again. Now they are telling me its system error they don't know when it will be fixed as they keep opening and closing my lines. Meanwhile I am being inconvenience as I use data to work. Kindly assist
