MTN service is pathetic!!!

I app**** for an upgrade on the 27th of November 2020 online. On the 1st of December I received the approval email for both of my upgrades. I was told on the email I would be contacted soon with the delivery details. 2 weeks later and still no update. I have emailed customer care and no one has responded. I even went to a MTN service center and the lady tells me it's at the warehouse and I have to wait that was a week ago and still no response. I called DSV couriers today and they said there is no parcel for me so which warehouse is it at??? As for the customer service agents at the call center, they don't have any clue on the online upgrade process cause all they do is transfer the call to get rid of you. I am very disappointed with MTN's lack of client service. Please can someone call me with some feedback on my upgrade!!!!
