"I tried to buy glasses from Glasses Direct. They took my money and then said they needed to ask me a question. I replied they could ask me via email. They insisted I call them but refused to tell me why. I suspected they just wanted to sell me more stuff. In the end I said either send me my specs or refund me my money. They refunded my money. I still don't know why they wanted me to call them. What a waste of my time."
