Poor online upgrade service

I ordered a upgrade device i have on a data contract online on 13 May 2023. It is now 30 May and is still did not receive the device as Mtn states 2-3 working days. I went to the Mtn branch to do enquiry, the consultant told me the device is with DSV couriers and i should phone them to do follow up. I am not satisfied that a online application should become such a hassle
