Disgusting Service - I want my Refund

I called Vodacom last month to cancel my contact. The 1st consultant I spoke to hung up on me after he heard I wanted to cancel my contract. I called back again and got through to a lady that refused to let me speak to a supervisor or a manager. She promised me that she would cancel my contract, assured me that there would be no debit in September and also said a supervisor would call me back. Its September now no supervisor has made contact, my contract is still not cancelled, I received a bill indicating that I am going to be debited again this month. I called this morning and spoke to Christel Nagiah she promised that someone will call me back within 15mins to complete the cancellation as "the cancellation was done for the incorrect date " its 45mins later and no contact has been made.

This is so frustrating and annoying. I would like a full refund of the money that will be taken on the 25th of this month and for this stupid contract to be cancelled.

I would also like something to be done with the consultants that failed to provide me with the service I deserve!!
