8TA is the worst service provider ever

My line has been suspended and now I have to live with the inconvenience caused by this suspension when my account has always been paid up to date. I called every day since the suspension and no one can tell me the real reason for the suspension but they can all tell me that they can see my account is not in areas on their system but I HAVE TO WAIT 72 working hours for THEIR MISTAKE to be fixed since it was an error on 8TA's side. I have lost business in the meantime while 8TA SORTS OUT THEIR PROBLEM when I never gave them a reason to suspend my account. If its a system problem why must the client suffer???? Totally disappointed with 8TA, my line is still suspended....72 hours have passed. Proof of payment I have, proof of the payment reflecting on the 8TA system I have too. Worst ever telecommunication service provider.
