Mobile Plus - No thank you. I'm not an idiot!

I notice that my previous review was removed but I'm adamant that I was **** too and were not given the accurate information. This company obtained my personal information from MTN, for which I did not give MTN permission to do so. A consultant from Mobiles + called me last week stating that she was calling from MTN and wanted to offer me additional voice and data. I accepted with the understanding that this is MTN and the contract was for R109.00 per month. Today they loaded a debicheck request for R20 000.00 which I have no idea for what reason and no warning. This is not acceptable and is not done in a trusted manner.
