Dropped car off at 0830 for mot and service for mid day finish only to be told at 15.30hrs that I had an option of a oil flush which meant that they hadn't even drained the oil yet( i declined ).Also there was a further hour delay while they sourced an air filter from the main dealer despite the car being booked in two weeks earlier. Recommendations were that a rear tyre needed replacing as it was 2-3 mm and three wheels required balancing.I immediately took the vehicle to a tyre company who replaced the front tyres weeks earlier who confirmed the rear wheels actualy had 4-5mm tread and the wheels didnt need balancing. Halfords also reported that the service light was on which is untrue,i actual don't know if the car has one. I take three vehicles a year to halfords but unsure if this will now continue.
