I'm sorry that you experienced difficulty in trying to reach me via the email address I provided. I tested it and it seems to work.
However, please try to send me an email instead at firstname.lastname@example.org. I will be happy to assist you in resolving this issue. However, at this point, I am unable to identify a billing or membership record for you. In the email you send me, please provide your full name, email address and postal code. With that information, I should be able to identify your membership record and will then take care of your request immediately.
