Guild Wars 2

I’ve been having troubles when trying to buy gems for already two months. First I used to buy gems via Pay Pal and it all worked out for quite a long time, but then a few months ago, Pay Pal didn’t work anymore, everytime I tried to purchase gems via PayPal, at the end of the transaction I received a message saying “Error finalizing your purchase” or something like that. Then I started using a credit card instead and it worked out for some time as well, but now it doesn’t work either! Now whenever I try to purchase gems with my credit card it gives me a message at the end of the purchase that says something about “Payment approval failed”… So basically I have no way to buy gems and it is getting very frustrating And I already checked that my billing info, the credit card number, the verification code, my passwords, everything is just fine so I don’t really know what the problem is now. I would love some help.

I already sent a request and I got this number " Request #75489 ", just in case this helps.

For some reason, i cannot purchase any gems from the Black Lion Trading Company. I have only used my credit card twice before. But now it keeps saying “Payment Approval Failed.” Yet i do have money on the card. Please, someone help me as soon as possible.
