Bad service.

I have a contract with on air tv which i took in October 2024, in Nobember it was working just fine,december it just went blank and it flicked the red light. I reported the matter and i was told that i must go to dstv outlet for the technicians to fix and i was told that they need to exchange it. I called on air and i was told that the courier guy will being me the new streamer. To this date i haven't received a new streamer. I have been debited for something that is not working,when i ask for termination of contract im being told that unfortunately i cant cancel i will have to settle the account in order for them to assist me. I am so disappointed on the service that I received from On Air Tv.
