dissappointed and upset

good day

I am extremely upset. I've placed an order on Saturday the 7th of December and paid the express door to door delivery fee. My package was supposed to be delivered yesterday 11 Dec 2019. I thought ok i'll give it another day. Then, this morning I called the call centre who advised me that my parcel will be delivered during the course of the day. I then called again at 4 pm and my package has still not been delivered. The lady on the phone told me that the package would be delivered before 4.30 pm today. it is 5pm now and still nothing. This is unacceptable as I was planning on wearing that outfit tonight as I had made plans with my friends. I would like to know, what is the point of paying the express fee if the package is being delivered late. I called the courier company, which is "Fedex" the lady on the line gave me attitude and requested a Trace number. I told her that i Don't have a trace number, only an order number which was in the email i received from MRP. I work in the service industry and this is not how I treat my clients. I know that it's the festive season but i am so disappointed. I don't think i will using this platform in the near future and I hope that this hasn't happened to other clients as well.
