money debited, no one has answers for me

Account was in collection, deposited the said outstanding amount( account is now up to date), I was told that phone would be unblocked after 48 hours but instead it took 6 days before phone was unblocked. On the 27th November 2015 R1000 is debited from my account by Telkom, I call 180 to find out why the money was taken because my debit date is the 1st of every month, the consultant doesn't know and tells me to call after 48hours, Monday I call and ask what happened, sorry ma'am I don't know why money was debited ONLY the billing department can assist but I can see that R1000 was debited, ok transfer this call to the billing department coz I need to know why money was taken after my account was updated and especially on a date which I did not agree on and no one had consulted me about, consultant says they can't refer me to the billing dept.<br> I then send a Direct Message to TELKOM on Twitter, I provide my details so they won't have problems trying to fix this mess, they get back to be by saying they will follow up and advice, this whole week no one says anything so I call again today and I'm told the money is not reflecting. WHERE IS MY MONEY?!???
