charged beyond set limit

<p>Hi,</p> <p> </p> <p>I have a data contract with Vodacom, which I pay R45.00 p/m.</p> <p>About 4 months ago i exceeded my free minutes and was charged R1800.00.</p> <p>I paid the amount and put a limit of R50.00. It worked fined until last month when now i have to pay </p> <p>R 476.60. </p> <p> </p> <p>I launched complain with vodacom but my matter is not resolved to my Satisfaction . They say call limit is not guaranteed, and they can't disconnect me when i am running a session?</p> <p> </p> <p>We tested this with the call center person who logged my complain. I switched off my router for about few minutes and switched it on. I was still able to go to internet.</p> <p> </p> <p>What they are saying is not true and there is a random mulfunction to there billing system, which they don't want to admit and fix, but they want us to pay for it. </p> <p> </p> <p>I am very disppointed with vodacom.</p> <p> </p> <p>Regards,</p> <p>Mpholo</p> <p> </p> <p> </p>
