Not in full possession of the facts

On the 17th July my son went into the Waterfront to upgrade his cell phone contract. We spoke to Charmaine re the costs involved. The phone was \included"in the package. we never received any documentation showing the phone was on a monthly account. On receipt of the account yesterday it appears there is an additional charge of R119 per month over 24 months for the phone. The phone cost R1500 which we would happily have paid if we had been aware it was NOT included! By paying monthly it costs R2856. We were deliberately misled. We would like to pay for the phone in cash and then continue with the actual contract."""
