Mercantila Does Know the Definition of the Word "Refund" San Fransicisco, California

We purchased three Surround Air Multi-Tech XJ-3000C (XJ3000C) Air Purifier, all of which are wonderful products.  The issue is that during the order process, the web site (through ZooStores) claimed that you would receive a $25 "refund" per purifier if you purchase it through them.  

When the order arrived, no refund items were included.  We sent several emails, all of which were not returned.  We called a few times, but couldn't get through.  Finally, after a 40 minute wait on the phone, I got through.  The person explained that the refund was for future purchases over $250.  

After quoting the dictionary's definition of "refund" to the person on the phone, I escalated the issue to a manager, Bridget, and she said that she could not refund the money.  I called ZooStores, and to their credit, they said that the wording is indeed confusing, and that Mercantila should change the wording.
