I am not happy with my experience. I ordered glasses from specsavers bank city in December last year. After receiving them I started using them January I noticed on glass was not intact which them lead to it subsequently falling out in March. Took the glasses back and was told they will be sent back to be fixed. A month later I'm told the lab broke my frame and they no longer have it in stock. All other options available do not fit me and they tell me they don't know what to do because it's not their fault. I gave them options 1. Replace my frame with a similar one as I have already paid 2. Give me frame similar to mine from any range or pay back my money and was told they will get back to me. Till today no feedback.

I have to constantly call and enquire about feedback as I require them for work. I am now experiencing adverse health issues due to my eye sight being affect.
