Can not download model as stuck on payment page

I recently bought the Soldier WWI France model for a game I am making but after I put in my details to pay for it, I have been stuck on the same page with no sign of it changing. The green pay button turned into three dots to show that it was checking the details I assume but its been like this for hours. I also checked my bank account and the money has been taken out too. Please can you help me so I am able to use what I have bought.
