Innovation bullsh

I bought a ford focus from we buy cars November 2017.it had an innovation after market warranty. Last year during December the aircon was not blowing correctly nd I took the car to Ford Vryburg whom referred me to an aircon company that diagnosed the vehicle and alluded that some component is broken.the quotation was 2200 and innovation refused to pay and the car is still under warranty.on their contract they cover the aircon for 4500.i even took legal steps against them what a pathetic service.
