Bad customer service

Very bad service, my car got ******, failed to recover it , community helped me to recover, when they supposed to come and install the new device, they **** to saying a technician called off sick, while I talked to technician an hour before,he had breakdown waiting for company to rescue him. The car got ****** again didn't recover it, my insurance settled the outstanding amount with the bank and they claimed from another tracking company as my car was having 2 tracking device from different company, now when I m claiming from them, they just come up with some stories, saying I lodged the claim late and I didn't submit my lockbook everyday, another one saying I was never had an account with them, very bad service.
