Caught out lying. Bought some specs, as you do, at the Sleaford branch in Lincolnshire. After a few days the right-hand lens popped out and the lens fell out hitting a concrete floor and cracking a little bit off the lens so, after a while, took them back. Lady in there 'fixed' the problem by using a self tapping screw but couldn't snip the top of the screw off which looked horrible and, as these were mid range glasses, and only a few months old I said I wasn't happy so she said she would change the frame. She made a big show of looking through a cabinet and, after a few moments of studied searching smiled hugely and lifted up a new frame. I went back later to collect and took them home after thanking her for the excellent service. However, later that evening I picked the glasses up to use them and the other side popped out so, out came my magnifying glass and... You guessed it, the self tapper was intact on the right hand side and the hinge on the left had simply failed, pinged open and, it was only because I was at home with a decent carpet that this lens didn't chip as well. Absolutely shameful, I shall be back there tomorrow, hope they won't lie to me again.
