Incomptetant and lies

Absolute joke of a company. I pay for my line and they lose the payment with their manual systems. I then send proof pf payment and still they cant find it. I then send bank statement proving it went off my account and they still refuse to activate my line. Their incompetency is beyond anything I have ever encountered. The online help centre said the line would be active 3 days ago but they have kept the money and still no line. This after billing incorrectly for 3 lines when I actually only had one. And magically the credit they were supposed to pay me back resulted in me still owing them money. What an absolute sham of a business. Disgusting service
