Back at it with concerns on sites i guess.

Vinted has been having issues with the card i have (capital one debit) since i first signed up. It keeps auto declining my payment no matter how many times my bank is called to confirm the purchase and to clear the payment.
My card has funds and everything and works elsewere by itself and google pay, ive tried mobile and website too. The wierd thing is both my accounts with capital one dont work- the card fails to save , doesnt work with google pay, and the error says that payments refused - im not sure whats going on and neither do the people at the bank? I just keep getting default messages from vinted as well and to use a different card that works , does nobody know what is happening, and am i the only one?

(I wish they used paypal..)
