brand new faulty hd pvr

I received a brand new hd pvr via courier from multichoice on the RR899 payment option<br> 1 I made an appointment with an accredited installer for installation. When they arrived we opened the couriered bag. In the box and in the bag there is no installatio voucher. I phoned the call centre and logged call***. They said i must contact field services for a voucher. I insist on a voucher being couriered seeing that the contract I have with dstv was that a voucher would be delivered. This needs urgent attention.<br> 2 audio sat agreed to install the hdpvr while we await the voucher. The decoder worked fine accept fot boxoffice and catch up. After 48 hours I again contacted the call centre. Who first advised me to downloaf new software. After this was completed I had no service and only error messages. So I phonef again<br> I was then advised to format the brand new devoder. I now have an error message E48-32. The call centre said that I now have to take the decoder in for testing.<br> <br> My agreement with dstv was for a brand new decoder and installation. It seems that I have been sent a fault unit without an installation voucher.<br> <br> And DSTV keeps passing the bucket to me... the client
