I've ordered a pair of cheap glasses, and they've not even processed the order yet according to the online tracking. The site seemed to be a UK company, with a UK number, but no-one was answering. I looked a bit further and it's registered to an office with about a hundred other companies. Looking further still I found 4 online opticians all registered by the same overseas agency.
They don't answer their main lines either, but I seem to have found a chink in MAK Media & Creations Ltd.'s airwall. The person on the end of line said he'd get someone to look into it, and seemed very surprised that his number was on their site. So here it is in case it disapears +44 20 70 60 70 55.
These two site don't seem to be registered to the same company, but have bits of the same text on their site, so I could be wrong, and plagerism is wrong anyway.
