Worst customer service and rudeness from the Arcadia McDonald's manager called Mahlatse

I came to McDonald's in Pretoria Arcadia and asked the cashier that I would like to redeem and she called her manager by the name of Mahlatse who is on duty right now 20th of February 2018 at time just before 20:00.

The manager came and told me that I cannot redeem twice on the same phone and said to her, I understand that I cannot redeem the same thing twice on the same phone in one day. I further asked, why the App allows the redeem of other meals from the same phone and asked this while demonstrating to her what I was talking about.

She said that's not true but because I am not going alone, I said we will use two different phones and she left and went back inside saying we must go to another store because she will never help us.

I asked the cashier to redeem from the other two phones and she called her but she told her that she was busy which was a lie because I could hear her even now with other McDonald's workers inside the shop saying "he will go, we will just close the drive through because I told them to help me before I leave from the drive through.

They even told the security guard to close the drive through and instructed all other customers behind me to reverse and walk into the shop because they don't want to help me.

This was the worst customer service I have ever experienced at McDonald's.

I always take it lightly that McDonald's is advertised to operating for 24 hours but every time a come here after 03:00 in the morning they say their closed until 06:00 but this is worse.

Why would the App only deactivate one meal that I would have redeemed on one day and leave other meals activated if I can order those other meals.

My biggest problem is that they can't help us even when we are using different phones.
