Losing business

Ive been having problems with my lines being suspended. Being a business owner makes it impossible to communicate with my clients when my lines are off. I paid the account. Ive been struggling since Friday 7 Dec 2018 to have my lines activated. Every time I phone its a different story.. 1. You have to wait 2 - 4 hours before the lines can be activated 2. We cannot verify your information 3. We cannot allocate your payments 4. You still owe more money Between Friday and today Ive paid R8400 just to have my lines activated. The call center is of no use! Hello Peter is my last resort.
