Very unprofessional service.
Yesterday I bought a $25 prepaid credit card and attempted to buy 18m from Yohogold.com, however before making the purchase I was told there current stock was only 12m. Logically, I figured I'd buy out 12m stock that night and buy the other 6m the following day. The trade went through and all was fine.
Today, after buying the other 6m I received a message stating that I had not purchased a high enough amount and the money would be refunded to my account. This was AFTER the payment had successfully gone through. No where on the site did it say there is a minimum purchase rate and the automated system, in fact, allows you to buy in increments as low as 1m. I now have to wait up to 30 days for my money to be refunded.
If you plan on using this service I strongly recommend you inquire about the current stock before finalizing any purchases. Though you'd be better off using a more reliable service that supplies you with any necessary information before accepting your money.
