Unacceptable service from Discovery Insure

I sent my car in for repair to the repairer that my Insurance asked me to use. I had Closed the driveway gate on my car, and the back door would not open. When i came to collect my car from the panelbeater they told me the lock on the door that was repaired is broken, and the insurance would not pay for a new lock, apparantley that is wear and tear. Not sure how it could be wear and tear, as after the accident happened the door would not open??I was not happy with this as the back door will remain permanently open, unable to lock. I took my car, and left, and then reported this incident to Discovery, who said they would get back to me. I reported this Friday Morning 29 Jan 2016, no one came back to me. I have spoken to Simon, Adam, Natasha, Minogue, and several others at Discovery in the last two days, and still am waiting for someone to respond.<br> I do not pay second hand insurance premiums, but am being treated like a second rate customer????<br> I wish someone could explain to me what is going on?????
