Groupon, Inc. Deceptive advertising, Refund denied Internet

I purchased a Groupon and paid $60 (I've attached a copy of the original voucher to this complaint). The original voucher clearly states, "the amount paid will never expire and may be applied toward any goods or services offered by the merchant if the promotion is no longer available." I allowed the promotional offer to expire in June, 2013.  Now, I went to redeem my paid $60 value toward any goods or services offered as indicated in the deal I purchased and I was denied the right to do so....  

Groupon has replaced my original voucher with what they call a "credit voucher." (I've attached a copy of that to this complaint as well). The credit voucher now states, "the amount paid ($60.00) will never expire and may be applied toward the original goods or services specified on this voucher." (I've placed a red arrow indicating this statement on the credit voucher).  Groupon has effectively changed the product/offer that was sold to me. Groupon sold me a voucher that stated I could always use the paid voucher for ANY GOODS OR SERVICES, and now they are claiming all sorts of exclusions. This is clearly false advertising and a bait-and-switch tactic. They are refusing to offer me a refund. I've attached a copy of my e-mails, in which I attempted to resolve this issue with the merchant.  Groupon policy on-line states, "if the business closes permanently or refuses to accept your unredeemed Groupon, we'll always honor refund requests. (I've attached a copy of this as well.) I asked for a refund and was denied one.  Groupon has defrauded me of $60.
