Can't upgrade to EOD?

Okay I've reached my limit of not having enough storage space in EFT. So i want to do the big upgrade and buy EOD. When i go to website EscapefromTarkov.com and I try to upgrade my game, it won't let me for some reason. I've tried with my credit card and PayPal, but when I try to confirm my transaction, it tells me to contact xsolla support for some reason.

I'm i the only having this problem?
