Terrible management s****s and poor customer service

Dissatisfied with the service received from Mcdonald's Berea. I went to purchase milkshakes and a meal from them yesterday. My order was 5 choc milkshakes and a chicken foldover meal with a passion fruit Mcfizz. First of all they got the flavour wrong on the Mcfizz. When I got home I noticed that the milkshakes was not looking right as 1 was dark brown in colour and the other for had very little flavouring or no flavouring at all. I then called the store and spoke to a lady by the name of Xolisile who says she is the chief manager of the branch. She has no customer service s****s whatsoever as she told me there was nothing she could do as we are not regular customers. Since when do you differentiate telephonically who your regular and irregular customers are..... At the end of it all I am still a paying customer. If she knew me she would have known that I in fact am a regular customer at Mcdonald's Berea as I get food from there weekly. What made me more upset was that she said I must come back to the store in order to have my order corrected as they did not have anyone to come out to my place to fetch the order after which she just hung up on me whilst I was still speaking to her. I then paid for an uber just to go back and have the staff's faults corrected at my expense. When I got back to the branch it took her like forever to come out and all she did was take the items away and gone...... Never saw her again. Nor did she come out to apologise for her terrible management s****s. I asked for the area or regional managers number whom I believe is Lillian and I was told they not allowed to give that out. I want Mcdonald's to have this sorted out and for me to be compensated for such terrible service received from this store as well as my expense of having to uber just to return what was the staff fault.
