Vodacom needs to take accountability!!

Vodacom Mondo phoned me for a contract, the phone which they offered and the one I received from Ram Couriers was not as promised, so I immediately phone Vodacom to re-collect the phone via Ram courier in the middle of August, I even phoned again afterwards because Ram did not come and collect. I saw on my statement that I am billed for that phone this month! It is UNACCEPTABLE!!!! very dishonest and unfair??? I also have a recording of this contract sale and the person is Desire which sits in Umhlanga.
