Why do you have to get quotes? They should be doing that. Also, tell them it is undriveable and needs to be towed. A month for assesment? that's bs, get onto them and tell them to come pick it up. My experiences with AAMI have been nothing but positive, someone ran into me, I called them on sat, monday a tow truck turned up at my house, I chose a repairer out of the 3 quotes near me that THEY got and 3 weeks later it was all repaired.
