I have been trying to get an invoice corrected for 3 months. My vehicle was picked up by the ALD from the dealership one month late, at my expense. Unfriendly by phone, no response at all. Accounting refers me to the 'customer service' who never reports! Nobody feels responsible, in the end the amount was simply debited without correction. I also wanted to be ripped off when I gave my opinion. Under no circumstances lease here !!
