Utter negligence

We have a few contracts with Cell C , but after my experience i wish they would pay R10 000 to get out my contract with them.<br> <br> Around the end of October 2014 we had lost a contract phone, and blocked the linesuccessfully. And week or so later we went into the montclair store and took out 2 new contracts. <br> <br> about 6 months later we get a huge bill on the line we had blocked in October. Called the Cell Call centre get a copy of the voice recording of this call to find out the consultant at the Branch called the Cell call centre that day and said that she was doing a sim swop and got them to activate the line just so that she could process the 2 new contracts without hassles, as it apparently appears now after us finding this out the hard way, that you can not take a new contract out if you have any existing lines that are blocked on your account, and now her negligence is costing us as they don't want to take responsibility as We were never advised this by the lady at the store, that she need to do that she told us she was activating our new lines, meaning the new lines. Now there's huge bill on that sim card that she never did a sim swop for and they won't take responsibility
