Insure with Discovery ... get a broken car back

Had an accident with my Mercedes and everything was working perfectly, then the nightmare starts. 2 weeks to accept the claim, 3 weeks to get parts, one of the parts were incorrect and doesn't fit, reorder required... more time.

Eventually everything gets done, goes to the agent and they send back a reply that there are wear and tear items requiring attention on the vehicle.

I get the car and I am missing 4 and 5th gear, sometimes not finding any gears, show the panel beater who tell me to take it up with discovery. An ECU check says that all the gear ratio's are incorrect.

Try and speak to someone at discovery and no-one is willing to provide feedback, the panel beater says they can't do anything cause discovery has refused to fix the "wear and tear" items but no-one wants to look and find out what the problem is...

Then discovery send the email that the claim is settled.... still a car without working gears... the repair manager... still getting back to me

...and the panel beater is still getting back to me after speaking to discovery on Friday morning...
