The Worst Department (Billing/accounts) that I have ever dealt with!

If I could have given a negative rating I would have. Webafrica's billing department is possibly the worst department I have ever dealt with. Over five emails spanning more than 2 weeks and 2 calls. Still no response, not even a one liner saying that they are working on their stuff up for billing me 5 weeks too early and erroneously!! I asked for my service to start on 1 July. How is it even possible that you bill a client who is already being billed by CISP also through Open Serve, it is one line! UNACCEPTABLE!
