Becareful, as vodacom just cust your account when trhey don't recieve payment taht comes off a credit card.
The fact taht i phoned and advise my credit card expired and that i would give the new number meant nothing even though i have paid the account every month since start of several contracts.
Then vodacom disable the account, enbable my voicemail box without my permission .
then when payment went through, sms didn't work, mms still does work, took off voicemail and they put it back, blackberry service still does doesn't work, and i have asked for help several times, trhey send a an email to do this and that, and after nothing works, so at the end of the day paying for a service on a contract, which you can't cancel, and you can't use the service.
I think the worst, ist Vodacom South africa just does care!
