Discovery Insure not the brilliance they claim

The most ridiculous experience with Discovery Insure involving a vehicle claim. I hit a pot hole in December 2019 which (telephonically) according to my mechanic damaged my clutch which resulted in the car not pulling or driving properly (slipping/sticking. Due to it being the festive season I called my insurance to inform them what had happened because I did not get a call following the extreme impact that should've been detected and that I would be traveling so I would formally put in the claim on my return. Once the claim was logged my car was collected to be taken to an assessor. My car was with them for 10 days without any comms from them. Everytime I would call I'm told that the damage report will be sent to me by the end of the day on 3 seperate occasions which never happened until the day I cancelled the claim. After speaking with a manager on the 11th day without a car someone called me to tell me 4 ******* excuses as to why I shouldn't claim. 1. I fitted a refurbished gearbox on the car ( which I never did.) As I bought the car as is 5 years ago. 2. The damages do not coincide with me hitting a pot hole (while they never opened the gearbox to check) 3. The assessor who examined my car is not a mechanical assessor so he won't know to open the gear box and check the internals 4. My excess will be more than the repairs.

So which story am I to believe????? I stated mechanical issues in my original claim statement so why wasn't a mechanical assessor sent out in the 1st place?

So Discovery Insure has had possession of my car for 12days as of the 29th of Jan 2020. I have since cancelled my claim to have it fixed myself.

I thank you for your pathetic service in totality as well as your pathetic customer services. After being a loyal client for over 12 years. My Family and I appreciate it we really do. The inconvenience was out of this world
