Mobiles plus - misleading sales

So about a month ago I get a call from Mobiles Plus selling me a cell phone contract and a funeral policy for R79.00 a month. then on the 16th feb my BIS goes off, I was not informed that this was going to happen and that it was now going to cost me an extra R59.00 a month. My account gets debt at the end of the month after which airtime should be loaded on my phone on the 17th of Feb 2015 I called all day yesterday and I get told that the airtime loading should not be a problem and can be loaded by the end of the 17th. the one consultant says that the BIS can only be loaded on the 5th of each month the other consultant says within 72 hours. I am ever sorry for agreeing to this contract this is the first month and not a pleasing experiencing. the consultants should inform buyers about the BIS and the call centre should not make empty promises and not deliver. if this happens in the first month the what is still to come and if you want to cancel your contract there is a penalty to pay.
