Debonairs in randburg square

I'm experiencing a very bad customer service in debonairs at randburg square firstly I sent my husband to buy me pizza chicken and mashroom they gave him a wrong order. now today I sent him to buy triple decker for R79.95 the cashier told him that the pizza R85 instead of R79.95 I asked him how cause I bought that same pizza last week was R79.95 the cashier was very rude Lerato I asked my husband to give her the phone so that I can talk to her but ,she instead I heard her insulting my husband over the phone I think we are not being treated with respect because we are from outside and we don't understand they language I then asked for the refund, she told us that she wont refund us the is no refund.
