Vodacom refuses to assist with problems

My phone reached it's cap and Vodacom REFUSES to lift my cap due to their incompetency and inability to do so. I receive sms' saying the same thing over and over again and when I ask for assistance the consultants refuse to give their names and surnames (these are supervisors I am referring to). <br> All they keep on offering me is to \up my cap limit"and that I have to wait 6 hours for it to be activated. 18 hours later and several calls later they have still not upped my limit NOR do I have use of my phone. I even went as far to ask them to remove the cap from my phone"
