In brief, I contacted Groupon and explained to their customer service rep what happened with the details of my order. They checked with the account rep who deals with VCS and contacted me back within an hour to say I can choose one of two options:
1) Get Groupon bucks to the value of what I paid to Groupon
2) Get my refund applied to the method of payment I used
I have already received an email from Groupon with the refund is being processed to my credit card.
Thanks everyone for adding to the thread as that simplified my contact with Groupon as their Account Manager was working on the resolution already. For those who do not contact Groupon I understand they will be sending out an email to all those who subscribed to this offer.
