*****elent upgrade made by MTN consultant

After receiving a phone call from a MTN representative, Michael Rosenberg, for a possible phone upgrade, I advised him that I would like to downgrade, as my phone was still in working order. He said he'll be able to help, would only need to reply to the email he sent me from MTN with my ID. Once this was completed I asked for details of the upgrade to be send to me but this was never received. When I received my first statement the amount charged was higher than normal, and upon inquiry I was told that I had two new phones taken out on my contracts. I never received any phone calls to confirm or signed any documents. This issue is still unresolved as MTN keeps sending me in circles and just claims that it is still under investigation.
