When I got my Giant SCR2 back in 2008, it had Alexrim wheels. The rear wheel spokes started breaking within a week, and as soon as one was replaced another would go. As it was through Bike2Work, Halfords agreed to send the wheel back to their HQ for a rebuild. They then stopped responding to me after the 4-day turnaround went over a week, then over two weeks. It took the work Bike2Work coordinator to get them to respond, and only then did they grudgingly admit that they'd lost my wheel. It seems their ploy had been to ignore me in the hope that I'd forget that I was missing a wheel and stop bothering them.
In the meantime, I'd gone out and bought a new set of wheels so that I could ride my new bike. (Mavic Aksiums - which were awful, kept going out of true and they shop couldn't true them as the rims were cracked around each spoke-hole. They only noticed the cracks just after the warranty expired, despite repeated re-truing that failed to last. Result - money down the drain and a lasting aversion to Mavic products)
Halfords ended up getting the local shop to take the rear wheel off a random bike on the shop floor (different wheel brand, with the wrong cassette on the back) to fob me off.
I really don't think the cheap Alexrims wheels fitted to new bikes are fit for purpose. (I've had some cracking Shimano and Fulcrum Racing 7s since the Mavics, as well as a hand-build pair I made on the EBC wheelbuilding course).
