Hard Sell - no support

OnAir used hard sell tactics to get us to sign up for a 24 month DSTV Explora Plus, threatening that our current decoder will soon be obsolete. We were assured that simple instructions would be in the parcel that would deliver seamless installation. No such luck. One local installer told us that he has quit doing lock-in installations because Multichoice do not pay him. OnAir say it's Mulitchoice who pay, DSTV say I must go through OnAir to find an installer. Classic catch 22, buck passing. Clearly DSTV/Mulitchoice have a problem and cannot get people to do this work at the rates they are prepared to pay, but that doesn't stop the hard sell. Anyone else had the same problem?
