Poor service on an expensive vehicle.

I bought a Ford Ranger 2019 xlt double cab in 202 still under factory warranty and motor plan. Took delivery and found that the indicators were flickering and 3 times faster than normal pace. Went back the next day and they could find nothing wrong and said its normal. 18 months later now out of warranty and motor plan we hook up a trailer for the first time. Trailer lights dont work. Try another trailer same storey. Call ford and explain. They ask to book the vehicle inn. Done. Get a call later the morning only to be told that the wiring is faulty and it will cost R2500 to repair. I call three times but no return calls. I then make contact with the Service manage Sandile and he reduce the price to R1950. I refuse to pay and fetch the vehicle. I take the vehicle down to our local electrician at Flamingo Square Table View. It took them no longer than 3 minutes to find a loose earth on the module below the front seat. All sorted and in working condition and the indicators now flash at normal speed.
