Disappoint customer

Feeling very disappointed. I placed an order for an upgrade with Vodacom on the 20th of December 2022, and received a SMS that the parcel has been collected by SkyNet Worldwide Express . When tracking my parcel it went out for delivery on the 21/12/2022..... Suprise in all of this is that I have not been contacted and my parcel has not been delivered. To frustrate the matter further, when I call both service providers, the call end with promises but no answers. Delivery is said to be 5-7 working days.... Well it is 15 days later and I still do not have the parcel, nor an email or phone call to let me know the status of the matter from either of the two service providers. What is the point of phoning and each time u have to tell a different consultant the issue, when we live in a world of advanced systems were one would think they would record a conversations notes and have records on they system. All I ask is a call from the manager at Vodacom and Skynet to please explain as well as give me a solution. All o want is the parcel delivered, is it to much to ask that after 20years of being a Vodacom customer that I continue to receive good quality service. Waiting for a responce the no false promises.
