I contacted the garage owner about the state of the rubber boot last year when I changed the balljoints and he said he would 'post me a replacement' without mentioning tracking. I've had to do this and pay for it myself so having a bit of a 'mantrum' about it
His words yesterday were "Sorry mate, the part failing is not my doing, I will compensate the part etc (warranty) but that's as far as I can go otherwise I am working for free."
