Not taking ownership and assisting me

I settled my 8ta account back in May 2014. Zama who worked at Telkom at the time assisted me and scanned the proof of payment into their system. I signed a cancelation form and everything was disconnected on that day.<br> I even received a call from their call centre confirming this cancelation. 8 months down the line I received a very rude phone call from their 3rd party advising that I had been handed over for lack of payment - I went to Telkom and was told that the proof of payment they had on their system was blurry and therefore they cannot help me.<br> This is affecting my credit profile as well as my health as I am 7 months pregnant and am in a vulnerable state.<br> Telkom needs to fix this and stop being ******
