No service but billed in full

No phone or internet for 2 days now. Fault no - 261CTK300116. No feedback from Telkom since the fault was reported. This is very dissapointing since I am having service interruption every couple of months for weeks at a time. Calling endlessly, waiting hours on hold, and no help what so ever. I literally have to beg for service. Even worse, Telkom has been ripping me off for months now. They have dishonored all the contract agreements with me. I am waiting for refunds since August last year for a contract I signed regarding the ADSL line, i was suppose to be receiving 25% discount on the ADSL line every month, the bill shows eg: month 5 of 12, yet the discount is not app****. I was promise a refund for all the previous months since August and this has still not been honored! To top that off, I am out of service again. I do not think it is fair for me to pay for a phone line and internet service that I am not receiving properly. Why is it so difficult to credit for service not given??? Why should I continue with Telkom when I am not receiving the service that i require??? Pathetic service is putting it mildly!
