MTN Online upgrade

In this Covid19 environment I've elected to do my contract upgrade via MTN Online. My upgrade was successful, even went through the credit vetting. I have not received any further information nor have received any correspondence regarding my upgraded handset. I have not received the handset although I have app**** more than 11/2 weeks ago. Contacting MTN Online is impossible, I used 3 different numbers and all the call center agents are able to do is send an email to Online - this has proven to have no effect
