Overcharging and false advertising

I received an sms advertising R49 airtime a month on my prepaid phone and I'd be charged R25 on my Edgars account. <br> <br> Now, I find out that I'm being charged R40 and my phone has been switched to contract - so I have now lost certain functions on my phone (eg called ID) that are central to doing my job. I received no notification of this change being made to my phone until I went into Vodacom and they told me that my phone is on a contract. <br> <br> It's absolutely ridiculous that you can enter consumers into contracts without their knowledge. This is in direct violation of the Consumer's Protection Act. I'm not even sure I received the airtime for the month of Feb, which is when this happened, but I now have no data or anything else on my phone, thanks to this little situation that RMCS has put me in. On top of that, the person I spoke to at the call center (Ref ***) could not have been less helpful, no one at the Head Office answers the phones and the Vodacom help number on your website doesn't exist. If this isn't fixed, if my phone is not taken off the contract and put back on prepaid within 2 days, I will take legal action.<br> <br> Well done on running such a fine establishment.
