Garage failing to road test work done.

[BusaMK]

Just picked the car up after having a noisy bearing and driveshaft replaced, which had been making a noticeably loud humming noise at speeds above 40. On the drive home the problem was still there - the garage has obviously misdiagnosed the bearing location and hadn't road tested the car. I regret not insisting on personally road testing the car prior to paying and driving home.

From the law point of view where do I stand with regard to getting a refund, or having the issue fixed at no further cost ( as I have paid for the issue to be fixed). Or am I better off claiming the money back through my credit card company? (If that's even possible in this circumstance)

Thanks. Called them and am taking the car back today. I hope they either fix the car at their cost or give me a refund on the work done in error, we will see. Still not sure on what the law entitles me to ask for though.
