Over charged

Ever since renewed my data contract from 2G to 3G my monthly payments went up for no particular reason because Vodacom has been debiting more than it is supposed to and their reason was I have exceeded my 3G monthly limit, then in October it went crazy where they tried to debit R 983.74 as compare to previous month of September were they debited R 337.29,<br> <br> I then again went to their store and they assumed that my computer auto updates are the reason to that which wasn't the case, again in November they tried debiting R 896.27 and December R 660.01, which I paid December I paid that R 660.00, but I'm left with arrears of R 2000 plus but I cant use my router to access internet because I'm soft locked.<br> <br> I then called their customer service after long conversations with them they eventually discovered that something called Opera Telecom (Pty) LTD [Email Removed] with contact *** fax ***, which I tried calling but its all machines that talk, I cant get to the bottom of this because vodacom claims that I have been registered to some site, which charges me R 35 or so everyday <br> <br> Hello Please help <br> Regards<br> TE Shuping <br> <br> <br> <br> <br> <br>
