Line still suspended

I have paid my account in full and and my line still keeps saying its suspended, this is not the first time. they say after my account is paid it takes 48 hours to clear but it never does. its almost 72 hours later. First i paid my account with the bill i received 2 days later my account have been suspended. when i login to self service on Telkom website it states that my account balance is R0.00. If this is how a company do business i will rather use wireless service providers. Telkom has the worst service ever.
