Worst service ever received from Vodacom

I received a call from Chloe Moses regarding my Vodacom contract which was due for an upgrade. I agreed for her to send me the phone and the tablet only yo find that I signed up for a new contract instead of an upgrade. After a long back and forth her supervisor Nandile Dambula got involved in the matter eith no success. I told them that since im unable to return the goods they should send me the Sim card .I've been paying for the data that i haven’t used for 3 months now.

This is the worst service I have received from this people and in the meantime my money is being taken every month.

I need solutions from Vodacom.
