Door-To-Door (1-3 Working Days)

I placed an order on MRP online on Thursday 21st December and paid the R45 door to door 1 to 3 working days delivery fee, so that means my order must be delivered today 28th December if you exclude the public holidays and weekend. I have continuously phone MRP call center and queried on social media as to when my delivery will be arriving as the status of my order has still not changed from processing and I have received no assistance from MRP agents. The agent I spoke to today told me my order has not even been processed yet at the On the Dot Couriers, what BS service is that? I am flying up to JHB today and my order was suppose to be here today. I expect my order to either be delivered today or I want the delivery fee refunded back onto my account and the order needs to be shipped to the new address.
