EVRI won't accept payments

Can’t pay for any EVRI parcels yesterday or today.
Added all my parcels to basket but when I try to pay I get an error message saying “Your card issuer can’t authenticate this card”

Have tried a different card ( Mastercard and Visa ) , a different computer , 3 different browsers ( Chrome, Firefox and Edge ) all to no avail.

Tried Paypal but the site won’t let me use Paypal unless I enter my home address. When I try to enter the home address I just get an error message.

Had to use Royal Mail for all my parcels for a second day.

Anyone else had this problem, or can suggest anything else I could try?

Thanks
