Poor after service and lack of parts

Very disappointed with FORD once a proud owner of a FORD Everest LIMITED I know feel let down and disappointed. Bought one of FORD most expensive vehicle’s and to find out FORD don’t keep spares is a shock! The problem started 5 weeks ago, first FORD could find the fault and told me problem was resolved after the third attempt I get told that there is a fault with the clutch in the diff and they need to order the part. Two weeks later after me phoning every day I get told that the part will only arrive on the 18 October 2018, then it needs to clear customs so most probably will only receive my car the end of the month. I then phoned the customer call Centre to complain, my question was why can’t they fly the part in from overseas like BMW does it takes them 3 days to fly in a part, the answer I got was FORD is not BMW well the point is what type of company imports a part that will take 5 weeks to arrive surely there’s a disconnect here. When FORD sold me, the vehicle did THEY disclose that all parts is not kept in South Africa and their lead time on parts of 5 weeks! NO. When purchasing the vehicle, I dint mind paying premium with the understanding that I will receive a curtesy car, like for like, in the event my vehicle is going to be out of service for a week. Well in FORD defence they did try and give me a curtesy car however there was no car available, so they arranged a car from EURO CAR Rental. The car was delivered by EURO CAR Rental. I had to complete a whole lot of forms and had to sign that I accept the liability of R 12 500.00 access in the event the car got damage even a small scratch will be classified as a incident. Used the car for a weekend and asked for it to be returned because of the high access in the event if a scratch this include a chip on the windscreen. Besides the car was only going to be available till 10 October 2018. My question was to the customer services agent what we are going to do now, I was told that because I returned the car I no longer qualify for a curtesy car. Well I was not prepared to drive a car with an access of R 12 500 .00 for a chip on window, I was also not given a 4x4 but a 4x2 SUV. Eventually we got nowhere and was told the supervisor will phone ?48 hours later maybe FORD HAS GOT SO MANY UNHAPPY CUSTOMERS that you got to wait so long?
