Telkom account horror

I have been with Telkom for years and have been a good payer. One month was skipped due to the ******** debiting my money and the payment date fell on the weekend so when Telkom tried to debit they didn't find any money in my account. So I expected the debit to be double the month after as I skipped. As expected again they charged me R200 more on top of the double they were supposed to deduct. 5 days later after they debited their money my connection gets cut off without any notification or warning, I called them to enquire and they claim payment doesn't reflect as it was debited by another department but does reflect that I made payment so I asked them to replace the connection and they claim it will be done in approximately 24 to 48 hours since they still need to allocate payment on my behalf. this is the worst penalty a paying customer can endure especially knowing the payment is made. They claim this is how they do things, my argument was why don't they make us aware or warn us this will happen after a debit is made? Telkom might be cheaper but they are the worst in treating their customers!!
