One lose ***** messed up my right to eyesight.

I bought my spectacles from Spec Savers Tygervalley last month. I even came to Hello Peter to write a good review for the service I received when purchasing. Now a month later, one day I am sitting at the office and just when I scratch my itching eye, Booom the lenses falls off and when I look, the ***** on the side got lose and fell off. I then yesterday took them back to Tygervalley hoping they will help only for them to tell me that I have to pay the excess fee or admit that i damaged the frame, which i refused to as I have never even a day not even dropped the specs. The lady assisting me insists i admit an claim through insurance and pay excess and still I refuse. She tells me about alignment and a whole lot of stuff I know nothing about and for all I know the specs could have came misaligned and they were not inspected in my presence when I brought them and they are showing me this misalignment with a new ***** in already and who knows if they did not misalign them in the process of putting new *****. I say this because of the continuous way she forced me to say I damaged them or something. I took my spectacles and left without paying or having them fixed and I am hoping Spec Saver will fix this mess. I HAVE Worn spectacles my whole life and this year was my first buying from SPEC Savers and now I fully regret as I have never had this problem before. To say I am DISAPPOINTED is an understatement.
