Very bad ,offhand treatment by numerous staff at the end of the phone. Despite being instructed to go to them by tyre insurance company Mapfre to replace a punctured tyre that was not repairable they told me they could not come out to me to replace the tyre and told me to drive it to them. Having explained that the tyre was not runflat and it would have to be changed where it was, they said i would have to wait 3-5 days, and when asked how to drive the car on a flat tyre the lady said she did not know as she didnt drive. They then said they did not have mobile tyre fitters at that depot. When i suggested taking the wheel off and taking it to them they said they had to see the complete car as it was covered by insurance. They would not accept photos and after much discussion finally agreed to send a mobile fitter out the next day, but phoned back to say they could not find a replacement tyre in the whole of uk but offered another which would not match. At this point i gave up and went back to the insurer and asked if i could use another local mobile tyre fitter and they agreed. They got a tyre next day and fitted it without drama. Shocking , awful service from National Tyres !
