Why can no-one let me know when my phone will be delivered???

Hi

So on black Friday 29 November 2019 I upgraded my phone on-line All good and well I do understand they had a lot of applications. Wednesday all the contract work was updated and payments made. When I called to find out when delivery on multiple occasions I just get put through from one operator to another until I am left hanging and have to terminate the call. On one attempt they did tell me that the phone will only be sent for delivery in another 3 to 7 working days. Really? Why? you already handled my upgrade. I'm already paying for the phone. Why so log just to send the phone. If I understand after this it can take another 3-10 days for delivery?

Anyways today is Friday again and I still do not even know when the phone will be sent to me as I have no waybill number. When I was put through to DSV no one answered. I left my number for them to call back. Still no callback yet.

and the delivery address I gave is my work address meaning in another 5 days I will be on holiday and will not be available address.

I left a few messages with MTN's customer service but 3 days later still no response

Can someone please advise what I must do? I just want to know when I can expect delivery.

Ps. Will never do the on-line thing again. Rather just go into the shop wait in the long Que and get it all sorted same day.
