I had to change my reading glasses as the pair I had had broken even though I have looked after them. I was greated with" I'm not changing" them in a aggressive attitude and this was from the manager. I had the receipt.
The manager then proceeded to call half of Boots to find a way not to change the glasses this took 15 mins. She then called a second store manager and finally changed them. What a unpleasant place to shop, you can tell the quality of a company when things go wrong. This was a bad experience.
