Absolutely disgusted

It is the worst service I received from Vodacom in all my years as being a customer at Vodacom. I went for a upgrade on my contract and I specifically asked for a contract that's not more than R200.00 per month. To my surprise I get an account of R1900.00, and this is not on. How the hell is this possible for being on a topup that I must pay this amount, I went back to the store, and the lady informed me that I had an open line *** its a does this happen if I'm on contract, I was informed that the settings has something to do with it, what settings, if you are on top up, surely if there is no money left on the contract how does it do updates, I'm don't want this contract as I'm not prepared to pay R2000 per month for a contract that I signed for R200.00, its definitely that last time that I'm doing business with Vodacom, very very disappointed, I was told that the money would be paid back to me once the debit orders gone through, I doubt that very much.... please sort this out of I will go to my lawyers for signing a contract which does not match... not a very happy customer I may say and I must add that the consultant at bay west mall in pe was very rud
