Today I had a fairly routine visit to Heathrow Service Centre. Complete farce, wrong parts, wrong details provided to me. Another customer had similar experience. He was given Uber credits and left SC only to return to be told the Alloy wheel ordered was the wrong one! I was told they planned to inspect a paint defect. When I arrived I was advised the appointment would need to be longer than the 1 hour I was told 2 weeks earlier. I also arrived earlier to take advantage of the free supercharging only to be told because I was not staying there I would not be "booked in" and would have to pay. I had undertaken over a 2 hour trip. This has to stop now! I was told a senior area? manager was in a back office visiting. I asked to speak to them only to be told "Oh! They're not customer facing".
