Bad reputation

I joined this in 2021 while I was staying in a dangerous area, and I had smash a grab situation and I was held at gunpoint, I had a remote that was issued to me by matrix so that when I am in in trouble I can press it, and I did press it and I continued pressing with no one coming to my aid until I made a way to find help, the following day I informed matrix and I am canceling due to what had happened and they didn't help me, the phone calls telling them to cancel since they record phone calls I assume that they have them on their side and now they keep on bealing me and I have been receiving phone calls from them and I constantly inform them my reasons of not doing any payments, now they recently sent me a bill of R6600 and I have been Informing them that I do not see a reason to pay this money
