'Sendgrid - Error while updating card details and impossible to contact any Sendgrid support
When updating card details, I get the following error:
[ThreeDs2_Authentication_Exception] Transaction declined.402 - [card_error/card_declined/generic_decline] Your card was declined.
The card details are double checked and seem to be correct. I tried opening a ticket on sendgrid or contact support via chat but apparently that functionality is broken on the official sendgrid site, so I'm trying my luck here.
Any help is highly appreciated.
