Telkom should be Failkom

I am livid with Telkom in July we were notified that our adsl line contract will expire on the 24th September 2021. My spouse and I enquired how we could cancel the contract and was told we need to go the the nearest Telkom. We did so in August, we went to the closest Telkom and upon explaining to the consultant she advised that if we cancel the contract in store it would cancel immediately but if we do it online it would be canceled within 30days. I asked the consultant that seeing that we paid a pro-rata when we initially took out the contract so in actual we were paying for the month ahead are we still liable to pay at the end of our contract we were advised NO as our contract ends in September and we won't be using Telkom from the 1st of October so we cannot pay as we won't be using the services anymore. Come end of September Telkom deducts for October I thought OK they might not have had enough time to close the books so I go to my bank and have the payment reversed. Come end of October again Telkom deducts tried to contact them with no luck hence why we went to the store the 1st time around still no luck back to the bank get it reversed and stopped too. Mind you in all this time No-one from Telkom has contacted me. Last week I found out Telkom has placed me on ITC what the heck for I don't know as I've never skipped one payment. I was warned about Telkom when I initially took out the contract but because Telkom was a fami**** name and I thought just this one incident that I knew of couldn't be so bad I flipping wished I had listened to my friends and colleagues who tried to warn me. If there is anyone that can assist me with Failkom in order to get my name of ITC.
