I ordered on 19th Dec and specifically added notes and email them regarding a particular prescription requirement. Glasses arrived around 30th Dec and they were thick as jam jars (I had ordered high index) and the prescription details had been ignored making one lens much thicker than the other. I sent them back 6th Jan and the amended glasses only just arrived today 1 month and three days later. I previously contacted them to get a refund and they offered £30 ish on an £85 order. Apparently, because I bought two pairs and they decided these glasses were the free ones.
