unhappy customer

Hi<br> My contract expired on January and I was struggling to cancel it due to the fact that the number was not appearing on mtn shops . Since after January I was not receiving statements and they were deducting R100 instead of R278 which was for1gig bundles . Today I'm shocked because my bill is around R2350 which was deducted unexpected and the number was blocked last month,so obviously I was not using and no statement or communication came prior . I'm so disappointed in mtn after doing business with it for so many years.
