PVR function not working

I have a the full DSTV package with the PVR funtion active paying R809 per month. For the past couple of months my PVR function has not been working. I cannot record, Catch up or use the BoX office function. set movies to record and it records half sometimes and the rest of the time it doesnt record at all. I called the Call Cetre 3 times and was told to do certain things which worked but nothing has helped. I was also informed that the issue would be resolved in 24 hours I am still waiting. At one point I was informed I need to pay an extra R100 to access the function, for which I am paying for already. I cant deal with this ****. i make payments every month on time, yet im paying for ****. i need this issue to be resolved. I have family that has this service and they dont have as many issues as me. I need a response and i need a response ASAP
