My daughter had her Volvo MOT'd at Halfrauds. Failed on wiper blade!
New pair of wiper blades fitted. A month later upon first use of wipers since test, she heard a scratching noise. The clip was cracked and the blade frame was sliding sideways on the window, scratching it. As they were 200 miles from home, they called in at local Halfrauds. They would not replace it but sold them another one and told them to take up the complaint with the original fitters!
