TELKOM - ISN'T THERE A LOWER RATING THAN ONE STAR???

I am not one to complain but this is utterly ridiculous. I entered in to a contract with Telkom in December 2019. My uncapped bill is R899 which goes off on the last day of each month. The company I work for deposited my salary on the 25th of January 2020 as this is a bad month. Telkom decided to debit my account on the 25th which obviously was successful and I suspect they changed my debit order date to the 25th as well (I did not). In February 2020, they attempted to debit my account again on the 25th which was unsuccessful due to insufficient funds. Furthermore, they added R202 to my bill as due to none payment eventhough this is not my fault. I get paid on the 26th which is why I agreed that debit to be done on the last day of each month as they have no other dates to do debits. They deducted, R1000.35 yesterday 13/03/2020 and then deducted another R1000.35 at 00h34 this morning (14/03/2020). I contacted them explaining that I did not authorized this to which they claim that my debit order is set for the 25th which I know is incorrect. In the first place, its not my fault that my debit order was changed which means they did not follow the agreed terms. I did not authorize an additional deduction which is pure theft. After this contract I will never buy anything from them again. I wonder what other "mishaps" awaits me during this 2year contract. I would strongly advise everyone who reads this, do not enter in to any long term agreement with them. They Suck!
