not assisting with query wasting my airtime

Since last night I tried to resove a problem on my hd pvr, Is unable to play back recordings, pause or rewind, the picture freeze. First the person assisting me was rude and I hang up the phone, none of them could resolve my issue and Ive waste over R100 in airtime, I got a new hd pvr decoder yesterday cause my decoder hard drive was damaged. I tired of phoning and not getting solutions, the call centre is becoming a waste of time. Can someone get a professional to assist
