Poor Customer Service From Mr D

I just had the worst experience from Mr D. I ordered a Big Mac Regular Meal and a Double Chilli Cheese Regular Meal which added up to R164.80 including delivery. 1. The food recieved was ice cold. 2. There was no cooldrinks given when the meal was delivered. 3. The drive Delan Dube was extremely rude telling me that it is not his problem It is Mc Donalds problem. I then contacted Mc Donalds at Hillfox on *** and was advised by Shirley that my entire order was collected and I need to contact Mr D. Shirley sent a photo showing the complete order that she handed to the driver. I then contacted Mr D and received even worst customer service. I was on a call for +-47 minutes and on hold for most of that time. The call was then disconnected from the agent (Zara.T). With no feedback I received an email stating that R50 was put in my Mr D wallet. My mom called Mr D back as the payment was made from her bank account and spoke to a lady who advised that the driver sent a photo confirming that the cooldrinks were not given to the driver at Mc Donalds Hillfox however she transferred back to Zara. Zara advised that she liaised with the manager and only a voucher for the cooldrink was authorized. My mom asked to speak to the manager and was refused saying that a callback will need to be made. My mom got irate and asked for the managers details. Zara advised that she needs to get the managers permission to give out the details. My mom advised that it is not true as we both work in a customer service environment and details are to be given. My mom gave her details and when she gave her cell number Zara said it is not the same as per the system. My mom confirmed that the manager can call on my number as it is the one on the system. My mom asked Zara to remove the R50 from the wallet as she paid R164.80. My mom requested a call back from the manager within 5 minutes and this has not been done. This in my opinion is very poor customer service from Mr D.
