Poor customer services

We purchased a MTN product two weeks back and still haven't received our product. We have been in contact with MTN and the transport company DSV and by that I mean we have been contacting them with no help at all. What has become of the major service providers where they cannot deliver a service that has been paid for. I am posting this message due to my wife experiencing anxiety attacks from the appalling service we from MTN, DSV and Rewards Co where we purchased the product online. A week after they promised delivery, we are still waiting for the product we already paid for. My wifes name is Adhika Manger, cell ***, product purchased - MTN uncapped month to month data package.
