Dstv insurance and their service provider bad service

I made a claim for my faulty decoder on 09March 2023. The claim was approved and I was given the name of the service provider that is BEAMSTAR COMPUTER AND PROJECT PTY/LTD, and I was told that the installation appointment was for 13th March 2023. Contacted the service provider, he said he won't come and install it I should come and collect it. He even gave me the directions to his work place. Went there without knowing that I was not suppose to collect it. He was not in his office, called him on his cell phone he said he will tell me when he is finished working on it. The guy was very rude to me. I called Dstv Insurance explaining how the guy treated. Thats where they explained to me that I was not suppose to collect it., which means the guy is a *********. They promised to call the guy of which they did. After the call he apologized to me and ask me to give him 2 him up until the 15th. The guy has not contacted me today the 15th. Contacted DSTV INSURANCE because I am not comfortable talking to the guy as he even chase me out of the office that day, they said on the system it shows that the appointment for installation is 18th, and that they don't have any control over their service providers. So I have been taken from pillar to post. I don't see my self taking any insurance with them. I am canceling even the ones I am having with them. It is close to a week now without a TV. Sad thing is that I paid for dstv compact package yet I can not watch TV. And been paying the insurance since 2015. I am so disappointed.
