Bad mannered cancellation agents

Vodacom contract cancellations *** obviously DON'T do what you ask them. When you phone, at some stage you must select #1 for an upgrade or #2 to do a cancellation. So you select #2 and then the agent (This time Nkoleleko??) keep trying to get you to enter into a new contract. My husband even ended the call and redailed as even though my husband told him he doesn't want to upgrade but have his number changed to prepaid, he keep on trying to convince him to take something that you DON'T want. The first call was 20 minutes when my husband eventually just hang up, the second call was 21 minutes and when we said we're going to hellopeter he stopped his nagging even though he kept us on line while apparently negotiating with his supervisor about add-ons to try and convince us to a new contract. Do they really think we can't do our own finances and so our own budget? SHAME on you!!
