Unfair treatment

Had a vehicle accident in June 2020. The person who caused the accident, did not have a valid drivers license. We were penalised because the insurance is on my mothers name, and i was driving this particular day.

Apart from being penalized and paid out less than the insured amount, i keep on asking for feedback on the excess recovery, as the person who caused the accident should refund the excess. I have requested feedback to more than one person at Auto & General, on 22/7/2020, 21/08/2020, 17/09/2020 & 21/09/2020. The only response i got was that the matter has been escalated to the recoveries manager. Up to date, no reasonable feedback regarding the excess recovery. i don't know if the guy is going to repay my excess. I do not get ANY feedback. Is this how easy one get away with driving without a drivers license, causing an accident where my vehicle was written off?? I get penalized and he doesn't repay my excess?? Terrible service to say the least.
