Mcdonads Plumstead putrid management

I had the worst experience I have ever had ordering take out today from Mc Donald's Plumstead. I placed an order with Mr Delivery at 13:40, my food had to be collected at Mc Donald's Plumstead at 14:14 and delivered to me at 14:29. At 14:40 the app still reflected that my food had never been collected. I had kids screaming due to alhunger and a toddler with a fever I wanted to feed before I administered his meds. I then drove to the branch and the experience there was far worse than I could ever anticipate. I was first given a whole host of stories all of which turned out to be untrue. I stood in the customer service parking awaiting my feedback and assistance in a hot car with a sick child and to no avail. I then decided to use the drive through to obtain their attention and only when I Held up a Queue at the collection area did the Manager make her way out to speak to me more annoyed at me for the inconvenience I am causing than concerned about the putrid experience I was enduring. At this point at 15:20 I was fuming, I was told the driver left with my food yet when I called home my mother advised nobody arrived as yet, I live 5mins away. My order was canceLled and a new one had to be placed. I eventually got my food and left and my kids had their lunch at 4pm. When I arrived home I received a call from Mr Delivery explaining to me that their driver Eric De Bruin was at the store at 13:56 awaiting my order and when he never received anything by 14:50 she instructed him to cancel and leave. She provided me with proof of this claim. I could appreciate her honesty even though I was not impressed with the lack of communication from their end to manage my expectations too. I called back to the store to discuss this with management and she conveniently could not take my call. I left my details for her to call me back and have not received any fork of contact since, reflecting her lack of interest with regards to the level of customer service her store provides as well as her complete lack of concern regarding customer satisfaction and impact. I work fr lom home and had to take over 2hrs out of my working day to resolve this issue costing me precious work time, unlike McDonald's management I take my job and customers very seriously and taking away from that left me extremely upset. I have spoken to others and based on the feedback I received this seems to be a common issue with McDonald's Plumstead and several others has had the same and even far worse experiences than mine with this particular manager. Going forward I will not purchase anything from this branch again and I will avoid purchasing food for Mc Donald's as far as possible too. Deeply disappointed.
