Telkom conning their clients

So end April i payed my invoice amount due without realizing that their was a mistake on my invoice which in actual fact i payed less than what i should have. then during the course of the month my account was handed over to their collection department who debited my account in 2 payments lastweek which was then the full amount due the short pmt of April and then May installment. so as far as im concerned my account is up to date then this morning i realized that all my number i have with them has been switched off . i phoned customer service and Desmond checked the collection account and saw that my account is actually paid he told me he is escalating the situation with them and in the same breath tells me that collections take 5-10 working days to update the system. So actually he is telling me that all my numbers is going to be off for all that time. they are so quick to suspend your line you pay what id due but then you have to wait 2 weeks for them to put it back on . what **** is this an eft takes max 2 days to appear into an account there is no way it takes 2 weeks. i asked around about other service providers and had to hear that the moment the money is paid your line is being reinstated that same day. What **** is Telkom trying. so if your phone is being switched off in middle of the month it means by the time it goes back on you get your new data and the time it was off that data fall away. you are paying for data that you haven't even used. As far as i see it that is *****ing and this cannot go on like this they are robbing people coz we as the client is losing out and they are gaining. What bull**** is that
