Vodacom robbing its clients

Last month I wrote about Vodacom and them not canceling my contract, wow last month they got it right by not deducting from me. But guess what, this month they deducted R44 from me. They do not respond to you nor do they fix their problems. To me this is **************** and *****ing from their customers. This is now been going on for 7 months. Am I the only one that Vodacom is robbing from or is there someone else that has the same problem? If so, please help me.
