Resuming a Subscription not working

I am beside myself with frustration, and frankly really angry. In September I renewed my bank card (same bank) and forgot to update the weMail billing. Until then the subscription was working effortlessly and my card was accepted by the weMail system.

Following this, I tried to resume my subscription using my new bank card, but got this message “Your subscription is not complete. Your card is under SCA regulatory (3D Secure). You need to confirm your payment to complete the subscription & billing. Check your billing email?xxx?to get your payment confirmation email. Confirm your payment & your subscription will be complete.” No such email comes through. I dont get 3D verification opportunities, nothing.

I have been told that my bank was rejecting because of lack of funds, that my bank needed to send the 3D verification etc, and that I need to use a different account (even though the bank was fine to start with).

I have now tried 3 different banks and have struggled since September (4 months) with the only response being that its my fault and I must resolve it at my bank. I contacted 2 of the 3 banks and they confirmed that no such request for debit was made by weMail / Stripe.

I moved my client away from mailchimp to weMail and based an entire project on this, and today the client realised that their automated services through the wemail plugin wasnt working – needless to say I am in such deep trouble, even though I have literally been begging weMail for help since September.

This is 100% a problem on their website and I am just hoping that by me posting here, will give them motivation to assist me as my countless emails have gone either ignored, or Im told to speak to my bank.

I am so frustrated!
