Hello Marc,

Thank you for reaching out and I am happy to help!
Just to confirm, I am seeing 3 unsuccessful transactions for the W3 Total Cache Pro from N Lorenz with the same email address. Can you please confirm this is the transaction you are referring to?
If this is the case, what I am seeing in our system is that the payment was declined with the message:

The customer’s bank has declined their card. The customer will need to contact their bank to learn the cause.

have you tried reaching out to your bank to learn the cause of why this transaction was declined?

Thanks!
