ENDLESS OVER CHARGING, INCORRECT DEBIT ORDER

I have been battling with Telkom for almost 2 years to stop contracts that were expired, they keep running them even after an upgrade and endless calls and visits to the canal branch. No one gets back to me. They owe me about R9000 to date. In January this year, my invoice for R2400 and telkom decided to just take 3K off my account. I called customer services and spoke to Thulani Mokoena , it's taken him 3 days to still not resolve a clear situation of error on their part.it took him 15 minutes to finally realise that all my numbers had nothing to do with it but a clear recon from invoice to bank statement which was sent to him. I am so tired of this. I have others on facebook that have numerous complaints about this as well, I am not alone. I want my money back. This is theft.
