Bad service

My Experience with WebAfrica is terrible. After having problems with my line transfer from my current service provider to WebAfrica I decided to cancel it. I was then contacted by one of the employees that my bill is still outstanding after even though I did not get the service I requested. I told them that I am not willing to pay the amount since I am not happy with the service, I was told that one of the managers would contact me. I was never contacted by the manager and since then my bill has increased due to the fact that the debit order was not approved. I do not like being unreasonable but this is ridiculous.
