Orders under review. Need Help

I have been buying from gameflip for a while now and now all of my orders have been put under review. I bought heatwave for the Xbox one and it got cancelled because I had to wait for 2 days while it was under review and now I bought another one 10 minutes ago and this one is under review. All of my payment information is correct and I have money in my account this is getting ridiculous! I would appreciate if I could get my item and not it be under review for 2 days to it get cancelled.
