Discusting treatment of customers

Checkers Meadowdale does not honor its Black Friday deals.A mistake on their part and when I call them on it I get called a **** then I go to prove it and see the cover up in progress.When one of the managers tells me I was right I asked then why was I called a **** and the person who called me a **** says she did not call me a **** then when I ask to see the name badge she walks off so I cant see it.I did not take the special because it was not about the price it was about getting told I am a **** if you cant handle a Black Friday don't participate I am sure there are other shops who wont mind my business
