I m very disappointed with Keyes Mercedes I been a long time customer from Keyes Chevy and I decide to trade in my lease with Chevy for Mercedes but I have done the worst mistakes in my life I m my mind I always wanted a Mercedes and finally happen but the process of the lease was a nightmare Keyes Mercedes took about a month to pay off my Chevy lease Mercedes failed to send the paper. Work and the off check to Chevy I had to contact Mercedes after 3 weeks from my original lease date because Keyes financial department never send the payment to Chevy or neither they contact me I had to contact them because Chevy collection department call me on my cellphone demanding a payment I was in shock about this I contact Keyes Mercedes and they transfer me to the financial manager a female lady she said she was going to take care of this ok but it was a nightmare as a customer i was expecting a better service from Mercedes being Mercedes a good brand but I was wrong I requested to speak to the General Manager but he never reach out to me it sucks because I m paying top $$$$$$ to get this kind of service very disappointed and this past week I had to bring my suv for service to get the finish touch protector and just experience another bad customer service form my advisor omg I can t believe it I never complain or write bad reviews but Keyes Mercedes what s going on i hope I do get contact by management regarding this review because this has to stop
