DSTV Explora PVR Deal

I am partaking in the advertised deal for the Explora PVR which was delivered on 29 March 2016. I contacted the DSTV supp**** preferred installer but he refused to assist me. He claimed that he will not install any more of the PVR's as DSTV is not paying him for installations already completed as well as the fact that it is old stock that is supp**** under the deal. His name is Colin from BAR Satellite in Robertson on number ***. I phoned the call centre twice to get a new installer, to no avail. In despiration I sent a mail on 5 April, reference number ***, which was acknowledged with a promise of a 24 hour turnaround time To date I received no further communication on my request that a senior manager must contact me regarding the claims from Colin. DSTV was very quick, SMS received on 6 April, to activate the new serial number P***, but I am stuck and cannot enjoy the new equipment. <br> Please assist.
