OUTsurance trying to reject my claim; going on week two with no car

My vehicle has an oil leak; I took it at Audi, a report was written and I sent to OUTsurance with the required photos. Instead of using that assessment and the photos presented, OUTsurance asked for more photos, and the claim now was managed by someone else. Now they sent an accessor at Audio without informing me - my vehicle is no longer there but with me - they refuse to come to me, asks I take it to audi again. Why should I be driving around a vehicle with an oil leak ?

What’s with the second guessing of an assessment already done by audi, and photos I provided ?
