Vodacom Cancellation Department

I've tried 3 times now to cancel my Vodacom contract with the Vodacom Cancellation department (***). All those 3 times the operator says they will cancel it and then try to sway me to rather opt for another month-to-month option. I described my financial situation and they don't seem to worry about the cancellation. They then say they have cancelled my contract. I ask for the reference number, but they refuse and say it will be send. Up to now I haven't received any sms or email to confirm my cancellation, as they state in their voice prompt. The last operator gave me a cancellation number that I can't verify *** I also didn't receive any sms or email reflecting this or any reference number. I'm fedup with poor service!!! These lying operators need to be fired, they bring a good company in bad reputation!! To top it all off this last operator asked me where I am going to get money to buy prepaid airtime if I cancel. It's none of his business to ask me that. It's personal. It is rude and unprofessional!!! I just want to cancel, my current company didn't pay me in two months. Vodacom is making it hard for me to promote them to anyone at this stage.
