> Also ask what work they did on the Pre Delivery Inspection (PDI) and for a copy of the report. This should tell you if they bothered to check it before they sold it to you.
The PDI should be with paperwork they handed you when you took ownership of the car. Look over it very carefully.
Ford's customer service team will be contacting you within one month of delivery to obtain your customer feedback. A very, very significant part of the Ford dealer's business plan is associated with their performance on customer satisfaction. Dealers used to spend £000's on unhappy customers to try and influence their answers.
The dealer will want you to be happy. It is unacceptable for such a simple and avoidable mistake to have occurred. Contact the dealer principal.
