Multichoice incompetence

We've been DSTV customers for years with a 3 way connection. Our primary decoder was ****** in February this year and we claimed from the Multichoice insurance, but instead of getting the Explora we claimed for, we received an HD decoder. I was advised to take it to Multichoice to get Explora. Multichoice told me they already they deactivated our working decoder that was still in our possession so we must keep the HD decoder we got from the insurance and they will do another claim for the Explora. Eventually we received it but ever since we did, we have been dealing with issues and couldn't get all our devices working as they were before, despite numerous lengthy calls and live chats with them. Eventually we called an installer who also wasn't able to correct the issue despite numerous calls to Multichoice in the 5 hours he was at our home trying to get us connected. He then advised us to go back to Multichoice to link all 3 decoders. We did that and discovered the problem was related to decoders that were faulty, which is the reason our attempts were futile. But this trip was also not the last resort because the agent at Multichoice didn't do his job correctly and we still had to call in again. R1200 for the installer to help us and many interactions with Multichoice later we are finally connected properly. I'd like Multichoice to reimburse me the R1200 we spent to get an issue sorted that resulted from them firstly, processing our insurance claim incorrectly and secondly, sending us faulty decoders.
