TELKOM YOU ARE IN BREACH OF CONTRACT!!!CANCEL

i changed my debit order date (from 25 to last day of the month)on the 21st of Nov and was told it would be effective at the end of Nov but that didn't happen. I called again after this and was told that i had changed the date after the cut off date and it would only take effect at the end of December which i understood. I was again debited on the 25th of December and when i called i couldn't get an explanation. i was charged R100 by my bank for the failed debit order.i logged a case ***1 on the 28th and was told that i would have feedback by the end of the day on the 30th but nothing was ever received. I called and spoke to Wandile Nxumalo and he told me that he cant make a decision by himself but he will have feedback for me by the end of day on the 8th but when i called to talk to him i was told he wasn't in the building and they couldn't find him so i ended up talking to Hopaney Liso who told me that Telkom does not credit or pay back regardless of whose mistake it was. i also got a call from a very rude guy whose name was Donald Motau telling me to pay so that the debit order date can be changed. no one has contacted me 3 weeks later.Cancel my contract, you are in breach
