False advertising

Checkers advertised falsely on there app and don't want to take responsibility for it. I went to 3 of their stores in the Western Cape only to be told that they know nothing about the special being advertised on their app. My husband and I were told that they would call us (Whalers Point Checkers) once they found out where the special is happening (21 April 2020) . To date we are still waiting for the call. We contacted their Head Office 4 times and each we were told that the customer care personnel are working from home and they would get back to us. I then received an email from Jo-Ann Hardy of Sixty60 requesting pictures of the item that I wanted to purchase. I rep**** and am still waiting for her to get back to me. And I have to date still not received any call back from their customer service. The special ended on 30 April and I still want the item that was on special. I took screenshots of the item and to top it all, incorrect sizes of the items were given and that is the reason why I am saying that they have falsely advertised items. It's disgusting how customers are treated and yet they are quick enough to take our money.
