Have you been receiving the whisky each month?
Has your credit card been charged?
Can you log into your membership account on their web site? And view the Account Details section to verify your email address, shipping address, membership type (one bottle or two bottle membership) etc.?
I wonder if your account setup has not been completed?
You will only receive the email when you have joined as a member and they have your credit card details and delivery address. Then the process is that if you don't specifically opt-out of the monthly offer, then you will receive it and it will be billed to the credit card they have on file. You can terminate your membership, change email and/or shipping address any time when logged into their web site using your membership credentials (email address and password).
If you are unable to make contact via email, then try their Facebook page for communication (I have not tried communication via Facebook, but note they do seem to be active on Facebook).
