Unapproved charges and upgrades on my account

Good day, please be advised that I've been trying to call the customer service number without any answer after 8 minutes. My number has been blocked as another account has been opened on my name without my consent. Vodacom Brooklyn is beyond useless with assisting and keeps on passing the buck. I have to operate a business on this number and now none of my clients can get a hold of me. Also I have content services charged on my account which I am not aware of, and with out consent. Please contact me, as I am unable to get a hold of your customer service department.
