Telkom complaint

I took out a contract with Telkom but they gave me false advertising. Telkom then cancelled the contract and said that i only need to pay the device at R689 per month for the remainder of the contract. All of this was done by Telkom Kolonnade branch’s manager, Tshapelo Mahla. He put everything in writing and i have the emails which he sent. This morning a R10,000 debit order went off my account. I’ve went into the store several times and spoke to Tshapelo to which he assured me, again in writing, that everything is sorted out with head office and the monthly installment will only be R689. I asked Tshapelo to reinstate my contract seeing that Telkom head office said that what Tahapelo said to us is not possible. He didn’t do that or even responds to ALL my mails. I’ve just spoken to Telkom head office and they said that they haven’t received any communication from Tshapelo. I’m on holiday and NuDebt took the R10,000 from my account which means that we need to go home now.

Please I’m helpless and need urgent assistance. I’ve phoned Telkom and they can’t help me, NuDebt doesn’t answer the phones or respond on their WhatsApp assist line and can’t get through to ABSA customer service.
