MTN has lost a loyal customer! Terrible service.

Giving MTN 1 star is too generous. I had an MTN contract that I wanted to upgrade to unlimited, they said I will need to cancel and open a new contract. When I did that, my application was declined. I have good credit and pay all accounts on time, why was my application declined several times?? And now they’re saying I should come back in 3 months and reapply. You’ve gotta be joking! If you don’t want me as a customer just say it!
