Cell C - daylight *******.

Cell C phoned me to offer me yet another contract. The sales person was persistent and refused to take no for an answer. I ended up taking out the contract. However, He added another contract to my contract leaving me with 3 contracts, where i only confirmed 2. Trying to cancel the unwanted added contract, but, it is impossible. They are constantly struggling with the "system" and i need to phone back... This is unacceptable.
