**** service from MTN and Mondo

I'm disappointed at MTN service provider. I have been an MTN contract customer since 2007, and have never had problems till now. I have recently had my contract upgraded with MTN, and I was dealing with their online customer support which is Mondo customer service. On the 27th February 2023, I had an upgrad and I was informed that the application process takes 5-7 days. It's been 21 days now, I have not received any communication from either MTN nor Mondo, instead I'm the one who calls to check how far is my application, and everytime I call, I get different stories from the customer service consultants. Or maybe I don't have money to pay or maybe it's because I'm an eletare black idiot, who is just being played by MTN and their friends Mondo.
