Telkom ******* Double debited no refund

Telkom has double debited us for 2mnths. We have tried to get the matter resolved and get our R3000 back through their useless call centre (spoken to and emailed a team leader called Paul Maphoto and 2 agents Nozihle Kubeka and Zinhle Ntetha). They do not respond to emails or return calls and their call centre is designed that you never get hold of the same people because when you call you go through to either kzn or gauteng and none of them can transfer you to either so each time you log a new complaint and get a new person who does not reply to emails. We were told the matter would be resolved after 7 days by Paul Maphoto after we emailed him our bank statement, to date nothing has been done. I cannot believe that in South Africa we still have institutions like Telkom basically *****ing money from people and nothing is done about it. No accountability what so ever.
