Cancellation Horror

This company is BAD we installed ADSL at our home but from the very beginning, the line was bad. They sent Technician out but the line did not improve. Because it's my daughter Matric year and she gets work from school via email and we had to have internet. I sent a cancellation request as I was not ha[ppy with the service as my daughter could not working I switched to MWEB which is much better. But now Vox wants me to pay R1035.00 for the cancellation of a service I have not been able to use at all. We have asked for assistance from the start but nothing substantial came from their side. If I don't get a proper answer from them I will inform the ISPA of the ******** business practices . I only owe the one month even though it started almost halfway through the month.
