I have to conclude they are really a SCAM!
I have to conclude they are really a scam. They supposedly sent my item, and reported it delivered. I opened a case and complained I not received the item. Superbuy support supposedly started an inquiry, confirmed the item was not delivered, and shipped back to warehouse in China (no explanation why this happened). Next update (can you guess it?) - item was lost. You qualify for x compensation, bla. But since I did not buy insurance for crappy postage service, I get 100 yuan compensation. Never to use your services again, Superbuy! you are a massive scam!
