Paying more for a subscription than I should. What a joke

Dyllan Canterbury the rudest Consultant in the billing department telling a customer don't patronize me for where they slipped up and don't understand there own subscriptions. The worst network company I've ever decided to sign a contract with. For a Monthly subscription of R499 a month for 24 months it's supposed to be one amount not tax extra or installment going up in 2 months and since I've signed even been charged for a full month I did not have the contract. They are very happy for a customer to just pay and pay and pay even more. Vodacom it's time for you to wake the hell up.
