Very bad service from SMD

Very bad and unprofesional client service. I have a car to sell so contacted the sales advisor not sure of his name but cell number ********** 301. First he gave me a very low value. After a day or two i said its fine he must come get the car. He asked for a photo of the registration papers and address. I send him allbhe wanted and told him that i will not let the car go out of my yard if my bank does not send me payment notification. He said its right and i told him he must let me know when they will come so that i can make arrangements . The next day he sends me a address and say i must deliver. I got ****ed off with this guy and told him to **** off i will keep the car. Argument followed and he deleted his massages on whatsapp. This is a verry unprofessional bissiness person.
