I had a very suspect experience with a company called smartbuyglasses UK. Basically after taking payment they sent an email asking for a scan of my passport or to pay again using paypal after which they would then refund my payment. I told my story on trustpilot and within 24 hours my review had been pulled and I was asked for evidence of purchase. I sent evidence and two an a half days later they have done nothing about re-instating my review, nor have they contacted me at all. Clearly they are filtering out the bad reviews for their paying customers. Steer clear of smartbuyglasses and anything bearing the trustpilot verification.
