False advertising to lure customers

They advertised heaters online and i bought 2x, when i went to collect i was made to wait for more than 2hrs, the security guy had to frequently call dispatch to remind them i was waiting. The dispatch guy eventually can with a story that the heaters were in bad condition i must check others then pay the difference or he will refund me, i then asked to see the heaters in bad condition seeing the ones he was suggesting were more than double the amount. we went to the storeroom, lo and behold even the damaged ones were not available which means they were lying once again.
