Theft an terrible service! Say away!

My father has been paying for itemized billing for the past 12 years and has yet to receive a single bill from Vodacom, because he doesn't receive his bill he is unable to claim his cell phone expenses and as such loses more money, because he is unable to see his receive his bill the account is always in arrears, and when he tries to get his itemized billing they refuse to send it because his account is R124.00 in arrears. We have received no customer service from this network and now that we have upgraded the operator has informed my father that he has to pay an additional R9. 00 to be able to see the numbers of the contacts calling him? I mean you can't be serious?! Now we have to pay extra to be able to see who called you? This is theft! The worst cellphone provider in the country! If this is not resolved my father will cease payment and sue Vodacom for 12 years of undelivered service which he has paid for.
