Worst Experience Ever

My wife booked her car in for a service Advised by Vikash to have the jets cleaned Gave the go ahead The very next day the engine warning light comes on brought car back to dealership Told that the car needs to replace a part approximately 4500 Agreed to have it repaired Ford fitted the part In a matter of hours after collecting the vehicle the engine light came on again Took the car back After further testing and diagnosis I was told the vehicle the vehicle needs to replace another part at approximately 6000 Spoke to the Dealer Principle who said they would be doing further tests After doing further tests we where advised that the Ecu /Computer Brain is faulty Cost to replace 21000 I was horrified to establish that Ford had removed parts from the vehicle and tested my vehicle with parts taken off another vehicle No Consent or Authority given My guts feeling told me to get a second opinion I did this and the problem was solved Car back on the road within a couple of hours
