AVG Ultimate purchased through Groupon - where to find activation code?

I purchased AVG ultimate through a Groupon offer. It's installed but there is no activation code provided. Can anyone help me find it? Thanks.
 

Hello Alison,
Thank you for reaching AVG Support Community.
Presently, there is no active reseller order of AVG Ultimate subscription on your AVG account that you used for the AVG community.
We're unable to process the reseller order from our end.
We request you to contact the concerned Groupon customer care and report this issue, they will look into the order and help you accordingly.
Thank you.
