Cancel subscription

The email address you have on file for my account is no longer available to me as I have left my employment. Two debits went thru my credit card this week but because of this I never received the emails. I have tried to cancel and request a refund but the form requires numbers from the emails.
Please advise what other options are available.
Thanks
