Been *****ed by Mtn far too many times

Im sick and tired of Mtn. Someone needs to fine this company billions so that its bankrupt and forced to shut down. Last night I bought 500mb of weekly data guess what, today its all gone. Today I bought R65 airtime. My data usage was off. No calls were made and no sms was sent. I tried buying 1GB weekly data which is R65 but i get the insufficient funds message so I check my balance and guess what, over R30 gone. I tried calling their customer care but the *****s made sure you cant even get through to their agents. This are not the only incidents. Mtn is making their customers pay for their fine by force.
