UChooseSmart XL

On 27/03/2015 I received an SMS from ***1 saying \Your upgrade to UChoose Smart XL will take place on 31/03/15". I inquired about this and was told that Vodacom has a lawful right to increase their charges and that I will be upgraded to this more expensive package. (Clearly I had no say in the matter). As from yesterday I am unable to access the internet or use Whatsapp. I called *111#. My subscription balance is R0.00"
