BEWARE Vodacom very SNEAKY with their billing.

I have upgraded with a new 24 Month contract on 1 December 2014. I have asked the salesman to cancel my Blackberry service. He assured me that it was canceled. Vodacom has billed me on the end of December 2014 and on the end of January 2015.<br> THEY JUST REFUSE TO CANCEL THE R59 BLACKBERRY SERVICE.<br> I have upgraded to Samsung Note and the Blackberry Service does not work on it since the beginning of December 2014.<br> <br> Can anyone help???or should this be taken to the newspapers.
