Appalling Service

I hit a pothole on the 3rd March 2020 and submitted a claim as I found my rim was dented. I sent all required documents as requested by IUA and they provided no feedback. I had to call them to get an update only for me to be told there's a discrepancy on my policy as the dealer I bought my car from listed the incorrect size of my rim. Now I'm being inconvenienced by something I don't have control over and to think I'm paying every month for this service now I have to wait for them to sort out their differences with Audi before my rim is fixed. This service is nothing short of appalling, what's going to happen should my spare wheel fail me? What then? Can't they fix my rim and sort out their issues with Audi after that?
