Pathetic service

Mac Donald service is pathetic and diecasting, they do not value their customers , their staff members leave on insulting customers . on the 6/03/2019 at 11:00 I went MacDonald's in Wynberg I wanted to order 2 big Mac but because I was in a rush I asked them how long will it take for the big Mac also one of the main reason is the (back staff, cashiers and I specific manager she is tall thin and dark in completion they always have a personal conversation talking about their weekend or what happen the previous evening issues with their boyfriend , we as customers we end up waiting and listening to their personal conversion) the cashier simply told me she does not know I must ask the back staff , when I asked her to do it herself she screamed " she is asking how long will the big Mac take " a lady from the back responded sarcastic saying 24 hours. I end up not buying anything the most humiliating thing is the same thing dark completion manager was there, when I went to her she simply said I love to complaint so I responded please not I will be sending a formal complaint she responded go ahead . in which I did I receive a call from another manager who did her investigation and new everyone who was involved however because one of the people I was complaining about was someone in a same level with her she told me she will refer this case to her branch manager to my surprise I receive an SMS saying the complaint has been resolved . I sent them another detailed email and with the time that they can call me as I am unable to use my phone at work I said call me 11:00-11:30 15:00-15-30 or any time after 19:00 I received 1 miss call from 011 number then an SMS saying they have been trying to call me I must tell them what time they could call me interesting enough they called at 14:00 I responded to the SMS I am available now you can call no call back. I call that same number on Friday 22/03/19 the gentleman who spoke to me told me that the complain was about no water, in which I corrected him and informed him what happened he told me that customer device made a mistake and send my complaint to his brach in JHB he will send them an email to call me back I gave him the same times to my surprise once again I received another SMS saying the complaint has been resolved. Which it has not this simply means when that shift manager and her cashier said I should go ahead and complain they new that MacDonald's foes not care about their customers and don't value them. I will never ever go to MacDonald's ever again even though it is very close to me I will rather go to KFC who is faraway from where I work.
