Very bad experience

Very bad experience. They keep suspending my line and tell me it's a system problem. This has been happening from last year already. I was suspended on Friday 15 March and they said it's due to non payment. I sent them the POP and my line was activated. An hour ago my line was suspended yet again and I spent 52 min with them on the line and I still do not know what the issue is. Whilst on the call with the manager my account was suspended yet again and the manager, Buhle enkosi couldn't tell me what was going on. No integrity at all!
