Hi guys

I wanna call Mtn customer service and scream "fvck you, you thieving kunts". I got charged #150 for shit updates i didn't request.
I don't want my line to get blocked cos over years i haven't used a sim for more than 2 months. Everyone be thinking i'm into some fraudulent shii.
To cut the story short, i want to tell their customer service to Fvck off!!

What is the possibility of getting my line blocked?
