Thanks for your comments, it's reassuring that I'm not the only person who has had problems with KF, and yes I will be using a Ford dealership in future for anything other than tyres or battery. Thanks again.

Result, put my complaint on their websit on Tuesday 21/2, got a phone call on 22nd to discuss it from some are manager. Said that I appeared to be a good customer and as a gesture of goodwill they would refund me £329.10, which was the cost of the alternator fitted in January 2016. Happy bunny now. Not too sure that I will be using Kwik Fit again though for service & MOT.

Had a new alternator fitted 14th January 2016. Took car in for service and MOT on 25th January 2017 with no known problems. Was advised that my front suspension needed attention which I thought might be the case as it was on a watch list from previous year, I was contacted during the day and told I need a new battery as the current on was only charging to 53% so agreed to a. New lifetime battery (£120). Picked car up at end of day, two days later battery was flat, contacted Kwik Fit, can you get it in to us, with a flat battery sure I'll push it I said, eventually they decided to jump start it then I could drive to KF for another battery, 2 days later flat battery, I had the car recovered to KF for them to look at it and sort out the problem, 2 days in garage they were mystified, fitted a 3rd new battery, 2 days later flat battery, again they jump start the car then decide to get an auto electrician involved, another day in garage, three hours after starting to diagnose the problem the auto electrician decided there was a definite drain on the battery but could not identify where it was. Manager at KF was at a loss suggested I take it to a Ford dealer. Took the car direct to Ford dealership and left over the weekend, Monday morning found out the alternator (fitted by Kwik Fit just over 12 months earlier) was faulty, £500 and a few hours later I was back on the road. My problem is now am I due a reimbursement from Kwik Fit for landing me with a problem I didn't have when the car went in for service/MOT, they say no as the alternator was outside its warranty period, any help would be sincerely appreciated.
