I dropped the car off at 8.30 at the Bishop Stortford branch on Saturday, just as they opened up. I was second in line and was told it would take about 45mins, which even then I thought was quite a long time to change one tyre. We went for a coffee and returned at 9.15 to find them still working on it. I eventually got my car back at 9.50! How can it take 1hour 20mins to change one tyre?! The garage was not even busy and we sat and watched two mechanics standing chatting while we waited. I received no apology or explanation for why it took so long. I will need the others changing at some point but, sorry, it won't be with National Tyres. I also had an email through asking for my experience but strangely twice it was unable to be delivered?
