Terrible service- no reply

Our car went in to be repaired at Renew it after we had a blow out. We had shocking service from them and got the car back with a broken aircon. We contacted discovery and the reply from the claims department was that it is a separate incident but they didn’t even ask any questions. Our aircon was working before it went to renew it. We then sent an email to the complaints department with no reply. We’ve never had a problem with discovery but after this we are looking to move to a company that offers better service. I’m also not sure why Discovery (a reputable company) uses such a shocking panelbeater as their service provider when they clearly have a terrible record (google reviews, hellopeter, etc) We hope this gets resolved quickly.
