No interest in replacing Nose Pads causing allergy

I bought an expensive pair of spectacles fitted on a Ray Ban Frame. First the frame was replaced because its paint started peeling within months of the purchase. Then I started developing serious lesions on the bridge of my nose as my skin reacted to the nose pads made from soft silicone or plastic. I have been back to execuspecs for assistance and neither they or any other optician are able to assist as the nose pads on this frame need a special tool which no-one seems to have. <br> Secondly, Execuspecs informs me that Ray Ban says they don't manufacture any other nose pads other than the ones fitted to my frame. Which I find difficult to believe. There is also a reluctance to assist as they have replaced my frame before due to paint peeling. <br> I have had to revert back to an old broken set of glasses and have not had any further assistance to resolve my situation.
