Norauto review: honouring a guarantee

I purchased a new battery for my Ford Fiesta (registration no. 6727 GRJ) on 02/07/2018. The cost was €107. I was pleased the the battery had a 3 year guarantee. The battery failed ie. I could not start the car, on 29/12/2019. Via my insurance company a mechanic came to my assistance and I was able to drive to Norauto in Miramar to claim a replacement for the faulty battery. At first the sales assistant told me that the paper work I had shown him was not valid despite having a written receipt, job outline and till ticket (factura). However, after complaining he agreed to test the battery to confirm the problem. I was asked to wait 3 hours! We agreed that it would be better for me if I returned the following day. This I did but was then told they would probably need to retain my car for 2 days. I explained that this was unacceptable and the test was then carried out immediately. As a result of the test, which I was unable to see, the technician claimed that there was nothing wrong with the battery and consequently that it would not be replaced. I knew this could not be correct and took the car (it just about started) to a Ford dealership, Garage Victoria in Las Lagunas, Fuengirola. The technician there tested the alternator, which was working correctly, and then the battery which was "weak" and needed to be replaced. I had to buy a new battery. I am left with the question, what sort of test did the Norauto technician carry out? Was a test carried out? Or was I considered an old man (72 years) from England who could be ignored? Perhaps in future your advertising literature should make clear that the guarantee given may claim to be 3 years but is in fact worthless. If my experience with your company to date is anything to go by, I expect you will disregard this complaint. Neil Hunter ([protected]@hotmail.co.uk)'
