I've just been informed that my credit card is not working

After receiving an email, I tried following the instructions from a company called Blue Snap - it is very complicated and difficult. 

I'm happy to replace credit card details or whatever - but if I can avoid a challenging episode of accessing my account details I'd be most grateful.

Please let me know.

Hello LearnButeyko,

Please be noted that BlueSnap is our payment processing partner.

Upon checking your account, I found that you have successfully upgraded your account again with the new credit card with order #INT140909-2611-53905.

Just to ensure that there is no double billing, I have gone ahead and cancelled your BlueSnap subscription. Your account is in good shape now.

How this helps.

Do get back to us if you have any questions.

Thank you!
