Booked a battery replacement for 8am - 12pm slot. Mechanic arrived at 11:55am with the wrong battery (not his fault ofcourse but an error from Halfords warehouse when loading) I then rebooked for 2 days later (Soonest slot they had) for the same a lot time 8am - 12pm. The mechanics (different from first visit) arrived AGAIN with the wrong battery. Surely Someone at Halfords had too much alcohol over the weekend! Thankfully the mechanics went to a local Halfords to get the correct battery and all was fitted by 12:45pm. I paid extra for an 8am - 12pm slot but I don’t see what for. The mechanics did their best anyway but Halfords do need to tighten their methods up. 2 stars!
