Disgusting treatment at Burger King Turhall Road ,Lansdowne

Most disgusting customer service I’ve ever received in my life l.Me and my wife were looking for a quick snack so we decided to go to Burger King at Turfhall Road /Lansdowne .My wife ordered online and we decided that we were going to use the drive through and just give the cashier the code for our order ,when we arrived at the window no.1 there was no one visible so we proceeded to wondow 2 in which I explained to them that there is no one there and they assured me that someone is there I then argued that we we stood by the window no one was there so they asked me to go right around again to window 1 ,so we did just that when we got there we hooted and that when a lady whom they say her name is Nono opened the window and told us to go back to the speaker and tell her that we have a code which was unnecessarily,I explained to her that I didn’t know that I must do that ,she then rudely shut the window and said she won’t help me ,I stood there until another lady came to assist,while the other lady was assisting I could hear how she was shouting and swearing at the background …firstly I was paying for my meal and it was not for free for that employee to treat us like that was so disgusting,would like to know if is that how the franchise treat it customers if it’s that then I would rather spend my money somewhere else and warn the public of how customers are treated at Burger King..
