Downgrading due to Upgrades.

I'm so disappointed with the upgrades department, whenever i have a service issue i receive the best assistance from client service but a call to update always leaves me worked up. These agents are so unprofessional that they get irritated when you ask questions and are extremely rude when you are not taking up the offer. This is the third time it has happened, the next time I receive such terrible service I'm cutting ties with vodacom and this statement will be my testimony. Do better vodacom!
