Hey @Salink,
Welcome back to the community and thanks for taking the time to post.
I'm sorry to hear of this happening to you and as @goslow suggested that appears to be a scam and we would never ask for the card number for any existing customers.
I would be happy to take a further look into this for you but would need to confirm a few details over via private message, would you like to do this and we can check your account?
Regards,
Steven_L
