Zinza was closing down while Groupon was sold

I bought a Groupon for a Steak & Chips at Zinza Bar in Longstreet.<br> When calling to book, the number did not exist and the address does not exist either. I found the restaurant today lower down in Long Street and the neighbours told me that it closed down in January - just before I bought the Groupon.<br> This is very bad Groupon !!! _ Last you see of me !!
