Delivery man argues with Client

After ordering and paying online, my pizza arrived. He took out the pizza, but the deliverman started arguing with me in front of reception that I had to pay, all with in ear shot of all my colleagues. I had paid online, I had proof on my phone,<br> <br> The delivery man then, stead of listen to me, decided to call in to his branch, all while waiting on him, my red dot slowly turned black. By the time he decided to leave, it was black.<br> <br> He then took the slip, as the phone wasn't being picked up and said outside, that he will be back if it wasn't paid. This is not a debonair way to treat client, Debonairs are advertised upon the debonair manner of their delivery.<br> <br> My dot was black and your delivery man was ill informed and any thing but debonair.<br> I want my refund, as I paid online and the dot was black<br> <br> Their branch number is +***6
