Wasting my time on a 11 minute call for nothing

My DSTV Account was stopped by me for a while. I finally decided to reconnect it. After 2 weeks or so I started getting error messages. Then the system reboots by itself and restart. Some days it would be fine for the whole day and sometimes I have to reset the decoder 3 or 4 times in a hour. So I went through all the fault finding(Swapped cables from the LNB, plug out the power supply for 15 minutes etc...) and possible error checking. Even Requested a DSD Upgrade. Tried resetting the system from the Website. Was working fine for 2 days then tonight it bombs out again. So I decided to call the helpcentre from my Cell Phone. I get through to a Lady that helps me. I explain to her that I have done any and everything possible. Is there something that she can do to help me, I Ask? Then the system reboots I Tell her the error code, she says she will send a reset signal. this didnt work either. So the after 11 Minutes she tells me she will escalate the problem. I ask if somebody will phone. She says no I must take my decoder in. REALLY? You couldnt tell me that after I told you I have done all the fault findings. Expensive Waste of 11 Minutes. Still no resolve. This is ridiculous.
