Telkom blocks account with zero balance i.e account paid in full

Hi I have recently move to Telkom mobile , unfortunately i have been without services since the 9th of July. When contacting customer care on the morning of the 8th just after 7am (Simphiwe Sitholi ***2) i was advised that my services will be restored within five hours. My account was blocked for none payment with zero balance. Let me explain. They call it a system error , your account is blocked although your balance on your account is zero i.e you do not owe them a cent. Sadly nobody in this company knows why this happen? So when i first logged a dispute , the consultant then send a request to the collections department to lift suspension as the account has a zero balance, which should take between 5 to 24 hrs to resolve. The following day i call the collection department on *** , and was informed that there is no such account with them as this account is up to date. My dilemma , customer care will not open my line , they will only mail collections , collections cannot open a line that is not in collections. I have been without services since Tuesday evening and nobody can resolve this. I even tried cancelling the month to month contract so i can port my number back to my previous service provider, this however is not possible as my account is locked.
