Ordered rear suspension and accumulator spheres for my Xantia 1.9TD. Asked for guidance (gave Reg. No) as not sure what was meant by 'Height Control'. Was given part numbers to order over 'web-Chat' however accumulator sphere had wrong connection. As it was GSF's fault, would they collect wrong part they stipulated and deliver the correct one FOC? No, had to take it to local depot myself! Instant credit for wrong one when returned? No, I will have to wait for it to get back to the main internet dispatch depot. I wonder if I will ever see that credit as no receipt was offered or given! Had bad selection advice given on a speedometer sender unit a couple of years ago for same vehicle.
