forced continuation with the Accounts/OverbilledAc

Good Morning!<br> <br> This responds doesn't mean anything thus the same song they have been singing. This is because i never exceeded the 2 gig data bundles they have been giving to me since. Surprisingly soon after the contract lapsed thus when they are saying i used excess data of which i am refusing, I am querying that. How can i use data for R2300, I don't do movies or games downloading so where is it coming from. Now they are holding me by force because all my contracts came to an end last month but to my surprise this month they have given me the data bundles and airtime. Upon calling them they are saying they can not stop it because it automatic and they keep on sinking me why? For the fact that its the internet modem in question, they should just turn the 2 line into prepaid line which are *** and ***. I no longer want anything to do with MTN they are *******. everybody who did business with them is crying. <br> <br> Help me please, because what they are saying its unheard off. How can they force me to still have their services which are no longer want because of their *****ed business style.<br> <br> Thank you.
