Unhappy with Eyesave.

I visited Eye Save Optometrist in St. Georges Mall quite some time back. I decided to try them again about 1 year ago. They did an eye test an I purchased a pair of glasses. Over the past year I have noticed when I am at a meeting and I sit in the front row I am unable to read the screen. When I watch TV and I am 3ft away I cannot read the screen. I find that Eyesave did not give me the correct glasses and I am very unhappy with the pair they gave me as I am not able to see clearly and i feel that they gave me the incorrect script. I know its a year but I wanted to make sure that I was happy with their service.
