Non-existent service, DSTV are effectively *****ing from their own installers

I purchased the Black Friday deal for decoder with installation from the DSTV website at the end of November.

Installer (whose details I obtained from DSTV's own call centre) did a great and fast job of getting me up and running, however when trying to claim his expenses from DSTV they have been unable to do so.

At first I phoned the call centre who advised me that this is a matter between the installer and "field services" however the installer was then informed that "this is a standalone decoder".

I then contacted the DSTV Care Twitter account, and was told it would be a matter of 24 hours.... 16 days and 2 "escalations" later, the issue is still unresolved and installer is still asking for payment.

I was charged for installation, but the installer has not been able to recover his costs. If I paid privately, DSTV would be *****ing from me. If the installer doesn't recover his due costs, they are *****ing from him.

I'm posting this here as a last attempt to get DSTV to do something about it, before I try my luck with the consumer goods and services ombud, or seek other legal council.
