False advertising

False advertising. Checkers advertised tomoto and onion mix 4 for R20.00. I went to Cornubia and Gateway and they don't have the special. When I queried with customer care,the response I got was the special is not available at Cornubia. The online advert doesn't stipulate stores that are exempted.. specials should be at all stores. I have a screenshot of the advert. Very poor service. And not a good email response from their customer service.
