Agreed it does appear that PX were true to their word and did return the part to fishers. However I gave PX the chance to rectify the fault to which they simply returned the failed part, choosing not to warranty the part. My warranty and point of contact is with PX not fishers or another bike shop, a point PX have acknowledged off forum.
And hora I was at no point rude or blunt, as you insinuated in your post. I followed the correct returns procedure, they simply were not interested in issuing a replacment.
In my case there was no question it was the part at fault, rather than a bodged attempt at trying to shorten a hose. Not sure how the wrong fluid was used, you dont even need to bleed the new shimano’s after shortening the hose.
Since this post I have received an appologetic email from PX customer services. And for what’s its worth (not an attempt at humble pie as I do think PX provided a very poor customer service) I will continue to use PX as their prices are very competitive.
Continuing on a positive note, only 4 weeks friday till I’m off to the alps!
