Let me explain the situation:

I wanted to buy a vampire blood for 8k, and I had 15k. When I first pressed buy item, it said "You do not have 8,000tc" so I refreshed the page. At the top, it then said, "You have bought vampire blood".
THEN, when I went to my inventory it was not there but my tc was gone! Please help, I will show any evidence needed. Just PLEASE help!
