Bad Service- Ferndale Branch (by Vincent, floor supervisor)

I am so dissapointed and humiliated by the service I got from your store in Ferndale, Randburg branch. Even worse from a person who's supposed to manage the staff. The floor Manager by the name of Vincent is so rude and aggressive you can even pick it up on your footage instore. I went into the store on a Wednesday morning to buy your daily breakfast, the lady who was helping me says Mam you will have to pick 3 differed options and I only wanted 2 options from the menu then I asked her if it's possible if she can still charge me for 3 but I will only take 2 as I don't like eggs and the toaster. Meaning I only wanted bacon and pork bangers she then said she will check from her Manager, and that is when Vincent came into the picture saying well its his rules it's either I buy the breakfast as per the store rules or I don't buy at all. My response was but the staff normally does it for me so why not today and I don't mind being charged the original price but only take 2 options then there was a client next to me whom I asked if she minds taking my other potion as I can't take it but I will pay for it. The lady didn't mind then Vincent continued to argue with me telling me I can't change their rules and I was trying to explain to him that I don't like his tone and approach why is he sounding so angry and shouting. Me and him got into an argument and he continued insulting me up until the cashier desks infront until I walked out the store after purchasing. My concern is how do you even hire someone like him and put him on the floor to work with people when he's not cable of dealing with customers on the floor. To say I'm shook and humiliated is an understatement. Immediately after walking out I called your customer service and spoke to Elize who assured me that my complain will be dealt with within 24 hrs of which I am still waiting for feedback. I really can't believe that this is how you as a brand treat people, you should be ashamed!!!
