salesman sells fridge as frostfree

On Sunday morning went to Makro Milnerton to enquire about no frost fridge they were advertising. Found fridge but wasn't to sure whether it was a frost free although a sticker on door stated that it was. I then called the salesman asking him if it was as i am looking for a frostfree fridge. He then told me that it was and even got the Bosch rep to confirm this. They checked stock and we purchased the fridge. Fridge was delivered and 12 hours later found that a layer of ice was accumulating on freezer and fridge. Checked Makro's advert online and it says no frost took the product code and then phoned Bosch believing that there must be something wrong, to wich they told me it is not a frost free fridge, but normal fridge/freezer combi. I now wonder what else i was **** to about, as they sold me an extended, warranty etc.
