Incorrect information - Consumer Complaint for Vodacom - Head Office

I have a contract phone which I took with elite mobile.... The number phone I'm sharing with someone, I received her SMS and phone calls with were suppose to be hers. I raised this with elite mobile and they said it's impossible. Now even my debit order is not mine but my was debited from my account and problem started on the second debit order now Vodacom says I'm on arrears and it doesn't appear that the debit order was made but on my banking statement it does. And the information for the debit order is incorrect. I need help. I called 135 and they said they will send an email so I can send my banking statement that shows the debit order but it's been 3days I haven't received any email. I call elite mobile they say I should call Vodacom. The phone will be suspended with something I didn't do just people being careless. I need help
