Rude dealer principal Gary Mancer at Basil Green edenvale and bad customer service at service department

I took my ford ranger to ford greenstone -basil green edenvale for the window not closing and Wesley the service advisor and workshop manager refused to assist me as I did not have my service book present but yet they can pick up all the service history on the system . I called three other ford dealerships Germiston,Midrand and bruma to make sure if they can see my service history and all three service departments could pick it up and said they cannot refuse us away as the service history is recorded on the system and has full service history!

I then called to speak to the DP Gary Mancer at basil green Edenvale to see if he could assist me . I explained to him my situation and he told me they won’t help me because I don’t have my service book . I then told him this is poor customer service and the call is recorded and I’m going to ford head office for this poor service I am getting as he got rude and refused to assist me (even after I called three other service departments and said they cannot do that) and he told me am I threatening him why don’t I go there to his dealership and he will show what he will do FACE TO FACE. He also threatened me to cancel my warranty and service plan if I complained which I wish him luck if he gets that right.

I cannot believe how disgusting and rude the dealer principal Gary Mancer is and how poor the service is .
