congratulations mtn for robbing the public

I have been with mtn for ages. Normally my bill is around R1800 pm. Last year mtn surprised me with a R7000 bill for data. This is although i buy data bundles. I proved them wrong and won. Last month they send me another bill of R7000 and the week after it jumped to R18000.00. I will lick the ceo's butt clean if he manages to get this money from me. Mtn are ****s and ******* and I will not pay this ridiculous amount. Every month they send me an sms saying the amount i must pay. It averages from R1800 to R2200. This i pay every month. All of a sudden it booms to R18000.00. All i can say is hahahaha. Beware of mtn people.
