National tyres Livingston replaced 4 tyres on my car this morning. No problems having this done and it was done very quickly. I drove home and took the locking wheel nut key out of the box to remove a wheel for a brake disc to be changed and the locking wheel nut key had been rounded off (stripped) no longer grips the bolt. I can only assume that National Tyres used an impact gun with the lovk key and this has caused the damage. (The locking key was fine beforehand as they managed to change all 4 tyres) I drove back to National tyres (Livingston) and asked the front desk agent politely if they wouldn't mind removing the locking wheel bolts from the car fro me as they were the ones who put them on.... The very rude and arrogant desk agent told me that I had caused this damage myself??? He then told me it's not there responsibility and asked me to leave!! Absolutely shocking service!! I expect to have National tyres remove these 4 locking bolts for me or replace the lock key which they damaged!!
