Terrible Service from Telkom

Early last month I contacted Telkom contact centre with the intention of updating my banking details, I was advised that details will be updated to be effective from End of June, Agent I spoke with told me that for end of May, I will have to do the EFT payment as they will attempt to run the payment on my existing banking details. On the 30th of May I did the EFT payment to Telkom but to my surprise, the same Telkom debited my updated account that should"nt have been as per Telkom agents. I spent 3 days trying to call them with no luck, they would put me on hold for too long or I would not get through. I then went went to the Telkom store where I was told that the EFT payment that I did reflects on the system but this is a billing query that can only be dealt with from the call centre. I was advised in store to reverse the payment from my bank and I did. today i received a text from the attorneys that my account has been handed over, they requested POP. when i phoned Telkom, they confirmed the EFT payment but they have added the penalty fee of R202.06 to my bill for this month that i refuse to pay, according to them,they still attempted to debit the old account and debited the new account at the same time. how incompitent is Telkom? I need this sorted ASAP. +***. I am going to report this to Ombudsman and Telkom CEO should it not be sorted.I called Telkom yesterday to dispute this penalty fee and I was promised a call back, until this minute, that has not happened.
