MTN is so *********** and it's a ****

MTN is so ***********, since last year, the store made an early upgrade without noticing it is an early upgrade, while they told me I was due for an upgrade, until today they are failing to resolve the issue the caused, telling me I must R9k for the early upgrade, they can go to hell, I'll never pay a cent from them, they can blacklist me for all I care
