Disappointed with their business ethics.

I am so disappointed with this company I had a data contract with them for two years which expired at the end of August. I called in at point of representation in Cresta to find out what options they were able to offer me for a future contract only to find that they had decided to enter me into a new contract for a further two years I told the consultant that if they decide to apply a new contract without my approval is not the way I would do any further business with them please cancel the contract immediately he said that an email would be sent through to confirm cancellation. This month they tried to debit my bank account for this contract I have requested my bank to return their debit order immediately which they have done. I am disappointed with Vodacom and their business ethics. I will not entertain any future business with them.
