no assistance and Im a new client

I purchased a Samsung galaxy last month towards the middle of the month on contract but I was not told but the extra fees changed eg: change from prepaid to contract, extra fees for contenting the other contract sim without my knowledge - i was changed for that as well and the debit was short so then at month end for some odd reason I was debited twice one debit went off and the other was returned cos it was not suppose to go off. Now this month I was suppose to receive the full package of R200 airtime and I again received half of that and no one was able to answer me when I called yesterday I was told they off line but no one till no even consider to give me a call and answer me as I left numerous messages to call me back. I'm shocked at the response from Vodacom <br> I need this to be sorted out or I will cancel my contract now my airtime is being used instead of my data which I cud not purchase as I receive shorted airtime.
