extremely annoyed!!!

I am disgusted by the service I received from a vodacom call center agent today.. I phoned to cancel my contract as it has been 24 months.. I simply wanted to cancel contract move over to prepaid but this lady was so persistent in trying to put on a monthly plan to receive airtime, apparently it's was gona save me money because by the time they cancel the contract vodacom would've charged me for 2 months already.. eventually after telling her 3 time that I don't want anything further but to just cancel the contract, she told hold on.. held on couple minutes and then the call cut.. no goodbye nothing enjoy your day.. I did get a sms saying they will cancel my contract afterwards but yessis how does vodacom employ people like this?! something so simple to do and I had to hear an entire essay..pathetic
