Absolutely useless service.

I upgraded om 25 june and for no reason (and no one at vodacom can tell me why), the upgrade have been cancelled. The result, im now being billed R760 instead of R360. No one can fix this, service requests dont help. Phoning doesnt help. Going into the branch doesnt help. Upgrading now doesnt help as im already being billed wrong. Just cancelled my one contract with vodacom. On the verge of cancelling my other contract as well. Totally useless service. After 16 years at vodacom, I might finally bid them farewell. Thanks for nothing.
