Bought a battery for my car from them. Then they tell me they can not fit to my model, too complicated! So I paid a garage as i do not have the tool to program it. 3.5 years later it fails, i return it under its 5 year warranty. They claim nothing wrong. Manager arrogant. Told me start stop not working because of a window module (without testing anything). I have it tested elsewhere as they told me to (battery specialist). They tell me certain types of battery fail in a manner they will not fully charge either on or off the car. However they tested alternator and wiring, its fine. Halfords still don't believe it faulty, wont do anything. Write to all 5 directors, no reply Store at other end of the country call me but as I'm too far away just tell me to go back to the store I went to before. Local battery specialist tell me Halfords have no idea with modern batteries. I call Halfords customer services they say warranty does not cover it being used! End up giving up ! Battery fails completely. Have to buy a new one elsewhere MESSAGE TO HALFORDS, STICK TO SELLING CAR WASH AND WAX !!! lets see if you can get that right?
