Poor services from DSTV multichoice

I called in last night to asked for a simple thing. I asked the consultant to unlink my brothers decoder cause it no more in use. I'm currently having 3 decoders which is one on my name and the other two is for my mom and brother. This stupid consultants at Dstv could not even do a simple request just to unlink the one decoder. He went to unlink All 3 decoders. He then put me on hold for 15minutes without coming back to me up until I ran out of airtme. I have to call back again and repeat my query and was told that it will be fix within the next 45 minutes till now. When I called back now at 08h02 and the consultant told me that they're unable to link my mom's decoder. Stupid service of Dstv can't even assist in doing 1 request right.
