MTN - Estate Late Transfer Process Issue

I am so annoyed with the process of how a transfer happens from an Estate Late to an existing customer. On Saturday the 4th June 2022, I went to The Glen Shopping Centre at your H/O Branch to do a transfer from my Late dad's account into my name we did all 3 contracts into my name successfully. The number that was the first one to be done does not appear on my profile escalated back to the lady that assisted me but she says she has sent it to the team to resolve it, to date no one has resolved this matter. The number is out of contract and I want to proceed with an upgrade but at this rate you making me doubt that I should be doing this upgrade. Always paid on time and just did an upgrade on my primary number but still has not been resolved.

I want to know how much longer must I wait for this transfer to be completed or should I just start cancelling my contracts with you guys and move to a provider that is prepared to assist me whenever I have a query.
