I DO admire your patience BB, but I guess losing your rag with them BEFORE your truck even arrives would not be good for future realings with them.
But they ARE a 'Toss of Bunchers' at HH Ford..When I go the staff are all nicey-nicey, yet very good at not understanding you..even when you take along your Thai wife..
My passenger-side electric window stopped working..booked-in, duly arrived there..never any room to park..waited an hour inside to be told the window-motor had packed up and it would be 2500B for new one fitting..ouch.
Told them I'd get back to them on it...found my pick-up covered in greasy finger-marks, the footwell was covered in bits of bared wire..
I thought Oh F.F.S.
Rang the previous owner of my car. She told me a 'window-motor' should be no more than 700B
(fitted). Popped into the garage/car-repair place leaving town on the Pala-U Rd..less than half hour later the window switches are doing their job, & the man would not accept 200B for his work!
All he'd done was 'pop' the door skin/liner, & re-inserted the main wire plug/connector.
This man will be doing all it's servicing now, and if I DO need work done at the Ford dealer I will consider going to the one below Pranburi.
On a more positive note, IF you DO need a canopy, bed-lid, nudge-bar, window tint etc fitting ,then the place on your left, heading Northbound just after the Shell garage (opp. 'Hua Hin Bike' cycle shop) do a good professional job.
