Very upset at 6am

<p>I took a contract with Vodacom for a router this was a contract for 199 pm 5 gigs of data. They charged me just over R200 last month but I let it go thinking it's prorata or something. This month they decide to ***** me over and take R481!!!!! How do you do this? This is not what was agreed on , they have not kept to their side of the deal and I would like to just cancel this whole thing as in no way has Vodacom been fair!!!!</p>
