no response, terrible service

I recently bought a decoder at Checkers Sandton (including installation) and it took me 2 days to get a hold of the call center of Aerial King, of which sent me straight on hold as soon as it picks up. upon getting a hold of an agent, i gave my details but was not told it took 2 days to receive call back, i was just told id get a call back soon. after 2 days i tried again contacting the call center, which was only answered after the fifth call. they said id get a call from the installer. after 2 hours, i still hadnt received a call. i call the center again and i asked for the installers name to contact them directly, since they hadnt done so. when i finally got a hold of the installer, my address was asked for and i even smsd it to them and they said theyd call back to see if they could be able to make it that same day. after an hour, i still hadnt received a call back so i decided to call again. i was told by the person who answered that they had already left my area and went to another area which they were called to and they were about to knock off so they couldnt install my decoder that day. when i asked them why they didnt contact me they had no answers. 5 days for installation
