They are a bunch of ******s. The idle issue has not happened again, they thought I was talking out of my ass. Perhaps justified....?
But I did find another issue, they fitted the new motor, now the driver blade jumps across screen. Pointed this out, along with the fact that it was OK before and they are new blades etc. He then blamed it on the blades my resonse was. "look, yoiu really are starting to **** me off, the car is in a worse start than I gave it to you in, any wonder that Alfa has such a bad reputation etc etc"
Anyway, he then bent - yes that right - bent the blade, when even I knew it was the linkage. I gave him the benifit and drove off. The metal edge now touched the screen. I went back in and growled, he took it round the back and now all is ok(ish)
The saga continues..... rant
For the record: Westover Alfa in Poole
