You got the first call. I would wait until the second call, say you had the photos evaluated at a body shop, and offer them 100 for repairs, and half a day's loss of use. The woman there said" this isn't let's make a deal". My wife said, in that case, you do what you need to do, and so will we. When they called again, I offered them: damage repair, one day loss, and no service charge. Ultimate check they got was for damage, half a day rent, and no service charge, which they cashed right away. I was clear in the letter that it was a settlement, but I still denied damaging the car or being responsible for any damage claims. They asked me to drop the complaints at the BBB and SD AG, which I said I would be glad to do upon receipt of a check for the full amount. Jamie, the Purco manager, tried to call me back, but I chose not to answer. I preferred to communicate in writing only, which of course they do not like to do. All of my communications with them were in writing, and sent by certified mail with a return receipt. Good luck. You should have more success negotiating on their second call.
