Having stopped for a break on my way to Northampton on 2 April 2016, subsequently, I had to seek professional roadside support to start my car. I was advised by the mechanic in attendance that the battery was dead and that Halfords who were located nearby would fit a new one. With every confidence I bought a new battery at Halfords and paid the ten pound fitting fee, having first ascertained that indeed they could fit the battery in my Audi A4. A very pleasant young man tried his best to do the job but after fifteen or twenty confessed that he had no idea how to remove the old existing battery in my car. He consulted his manager who also drives an Audi A4 and was told that he would never attempt it to remove the battery from Audi car for fear of damaging the neighbouring electronic wiring. Sadly, a clearly embarrassed and the very apologetic young man gave up on this job, refunded my money and jump started the car in order that I could progress on my journey with a dead and semi useless battery. I eventually succeed at having the old battery removed and a new one fitted by a garage mechanic. This entire procedure took him fifteen minutes and although it required unscrewing an extra nut that was not easily visible it did not present him with any difficulties because he knew what he was doing. In conclusion, I feel sorry for the man at Halfords who tried to change my battery, somewhat surprised and disappointed that his manager did not consider it was important for his store to be able to change batteries in all car makes and not just some of them and totally bewildered by Halfords in that they claim and charge for fitting some items, such as batteries, which they sell in their stores and yet they do not appear to give their staff adequate training.
