Saveology Austin Texas illegally represented my business and took customer's money with out merchant consent Austin, Texas

Saveology distributes group vouchers for a massage sale that I never ran with them, in addition to not running with them ( i ran with juice in the city) Saveology changed the redemption period to a year. These vouchers should already be expired as of september 2012, yet I have people calling in to redeem them thinking they expire in march of 2013! 

They changed the terms of a deal I ran with a whole different company and called it their own.. then changed the terms without informing me, the merchant or getting my consent. This is out right theivery and I will no longer redeem their fictitious vouchers. I am deeply upset at the misrepresentation of my business with this company whom I have never agreed to do business with.
