Poor delivery service and poor customer service

On the 23rd August I ordered my meals which included McFizz passion fruit for delivery. My order was delivered, instead of McFizz passion fruit, I received yellow soder water without a sugar or taste, not what I have ordered. I had to throw away that because I couldn't drink tasteless soder water. I laid a complain. I received a call on 27th August from your call center , the guy promised that they will deliver my McFizz on the same, however there are no drivers in Bellville Mcdonald. I waited, till today I have not received my McFizz. To my surprise, instead I received a sms this morning stating "McDonald's Case INC-93CE0-45EEFB is resolved. If you have any queries, contact us on ***." How come while I was still waiting for them to deliver my McFizz and its been a week now.

I am a student and I paid for my McFizz. You are taking my complaint for granted because its a small order. As a student, that's a lot of money for me. You have to learn to treat all your customers and their complaints equally and take them serious. In my case, you took long to respond to my case, you **** and said there are no drivers to deliver my McFizz, while you know you are at fault and you still don't make an effort to make sure that my drink gets delivered . On top of that now you are lying and saying that the case is resolved while I haven't even received the drink. You disrespectful, you are ***** and you don't care about customers with small complaints. I am taking this further, I am going to teach you that all customers are equal and important. You are being silly now and disrespecting me.
