A seller who would like to charge me an accident damage when I took back the lease, which also had the vehicle. However, it was repaired in the same house and paid for by the opposing insurance company. The seller didn't want to worry about it and referred me to the BMW hotline. Only the service consultant, who is not responsible for this, was interested in solving the problem and was able to find one after consulting the seller. Thank you again and the one star.
But what happened after 2 weeks shocked me and disappointed me deeply. I received a payment reminder for an invoice for a rental car, which I had never seen, let alone driven or rented. Incidentally, I had also not received an invoice.
In summary, I can only say that I will never set foot in this house again for no money in the world.
