Error message when trying to check out

The error message--" Your payment details couldn't be verified.Check your card details and try again."

I have tried at least two different sites to try and buy this vape product.But whenever I try to check out with shop, it ends up giving me this error message, i've used three different emails.I've checked my shop account to make sure all my information's right.I've even tried to do it as a guest.I've tried to use different payment methods each time.It took the payment and put it on hold, but nothing actually went through.As a transaction or a completed transaction, so now my money's on hold and I have no actual orders.And shop won't work for me.No matter what I try to buy

Has this happened to anybody?Is this currently happening to anyone?And has anybody figured out a fix to it?Or do I just have to stop buying things online completely?

When i've searched up this error message, it seems that merchants who use shopify also have had this issue by their customers Telling them and when they reach out to shopify shopify just plays dumb
