Case closed without feedback & unhelpful CC agent

I logged a case with the TM Call Centre about an amount on my statement I have been charged that I know nothing about. I get given a case number and told it will take AT LEAST 10 days to resolve. Fine. <br> I wait. Nothing.<br> 2 weeks no feedback I'm told I will be called back later today.<br> I wait. Nothing.<br> Today I call again for a third time and the agent Sizakele Hlongwe says the case was closed.<br> 1. How is a case i logged closed without my knowledge?<br> She says that the manager or something will call me back. I say, if he doesn't as he hasn't, what should I do. Her answer is that I should put it on Hello Peter so here I am. A month later with an unresolved but closed case and still being charged for things I know nothing of.<br> How on earth do I pay 2K every month for the total of my services but I can't be told about a query FOR A MONTH?????? How?<br> <br> I query the Telkom account on twitter, it responds to all other queries but blatantly ignores mine. How?<br> <br> I will need for this case to be resolved otherwise I will cancel all of my services with you people.<br> If I don't get feedback about this today, it's over between me and Telkom.
