Feedback from MTN is the worse

i Upgraded my Cellphone contract on the 29th of November 2021 via online application, received the confirmation letter that they have received my application, thereafter they need documents that i send to them, then everything went dead, then a lady from mtn phones me and tells me she will assist me with my upgrade, i have send everything through email to her and again it went dead, it is now 10 days later and recieved a email saying everything is in order but nobody phoned me to confirm delivery yet, if i can just get an update on when will the new phone be delivered but no that is to much to ask. i want this to be sorted out within 24 hours please, why the hold up with online applications, if i go into the store they ask ID, fingerprint and whala you have your new phone, now it is being 10 days already.
