I had a new tyre put on my car at Kwik Fit in Wrexham to which they rotated my tyres back to the correct place very kindly and grately, but ever since I drove at 70mph my steering wheel would shake, so I went back on the weekend and asked if they could take a look at the balancing and explained it was at 70mph, and the rude woman response was 'Our machines only do up to 70mph, so if your driving over that which is illegal anyway, there is nothing we can do about it.' So i explained this has never happened before to which she explained 'we have had other customer's complain about the wheel shaking, but as it's over 70mph there is nothing we can do' to which she then said they could 'check' but it's a 2 hour wait, to which i refused as the way i had just been spoken to! To which i got a second opinion who then advised me this was rubbish! I went to F1 autocentre the next day, and said the same thing to them, which there was No Problem with the 70mph 'limit', to then find out 2 of my tyres had been counter balanced and were completely off by 20! Only go to Kwik fit if you want to mess your car up or be spoken to rudely.
