Disappointing service from Telkom

There was a problem regarding my bank and debit orders and I wasn't aware that my telkom debit didn't go through and my services was blocked . I then immediately contacted telkom after receiving various messages from them about handing me over to collections and lawyers for not paying my account, I spoke to the lady over the phone and I had told her that I wasn't aware of this and its not my fault and telkom should make a note of this and I don't mind them double debiting me at the end of the month. She told me there's additional collection fees that I need to pay and so on, I then made arrangements to do a eft payment to them but she advised that it will take 15 working days and I should just wait for them to debit me because I'm closer to the date, so she made a note on the system for them to debit me of R1600 at the 29th. I waited on the 29th but still nothing so I waited again and on the 1st of July they debited me for the agreed amount R1600 plus another month's billing of R782! When I called the call center the guy had asked me when did the payment go off and I said it went off this morning and I have been charged 3 times and on top of that my account is still blocked!! He then said that there's nothing we can do( Nduzo) because it's not reflecting on they side and once collevtions receive the payment they will unlock my account and will take 7-14 WORKING DAYS TO BE UNBLOCKED AND REFLECT. Which I can't understand why because they took out almost R2500 from my account and they don't want to rectify it and reverse the extra amount that they took out all he said was its at collections and there's nothing that can be done and I have to wait , so now I must pay triple for services that I'm not even using cos I must wait half the month for payment to reflect when it's already gone off my account. This is very disappointing and unacceptable because I am a loyal customer to telkom and I never did miss a payment expect for this the first month in 5 years that I have my services with them and this is how they customers get treated
