I recently requested a headlight replacement in Halfords Hereford. I was offered a charge of 12 pounds to change the bulb and an alternative to cover two bulbs which I declined. The technician then guided me through a complete light check. At first, I thought this was good and helpful. He then started banging on the back of my car. I got out to see what he was doing. He told me that I had a number plate light out, but it came on when he banged my car with his hand. My defences were down, so when he asked if I wanted it replaced at the same time, I said why not. I was taken to the counter to pay and as soon as he indicated to the casher what to charge for, he disappeared as quick as he could. I was charged 27 pounds plus. More than double the agreed price for the headlight to be changed. And I never saw the number plate light unlit. So I didn't know for sure if he was right and I made the mistake of trusting him. Bulbs don't blow like that. They either blow or work. Alarms bell should have rung in my head at the time, but it was leading up to Xmas and I was busy as a consequence. Another review I came across was that Halfords train that you can always find a problem with a car. I have to wonder after this experience whether that may be true. I would recommend keeping your wits about you and only insist on what you know needs to be done. For me the trust has gone and next time, if I ever do go back, I will check all of my other lights first myself.
