Discovery insure stress on a 73 year old

I had hail damage to my car and put a claim for same. Discovery insure found the repairs to be over the cost of my and decided to salvage my car. They informed of the decision and I decided not to proceed and go the private route and thus informed them. The next time i get a call that the salvage company was coming to collect my car and i call discovery and they tell me they forgot to cancel the salvage and update to say i'm proceeding privately. we settle that and I forward them quotes of the private company they approve and i sign the relevant papers and i thought claim was finalized and payment will be made. Two weeks later the claim handler didn't process the payment. I am 73 year old lady and had so much stress with this company and nonchalant behaviour from their claim handlers.
