Billing for Suspended Services

My account fell into arrears, however, Vodacom suspends your account whilst continuing to bill you for a full service, resulting in losing the airtime bundles you are actually paying for. Most service providers, like DSTV, Telkom, MWEB etc, will cancel/suspend your service and not ALSO bill you. How is it right that your cancel the service, delete the number and continue to bill for the service, and if I pay all the fees since suspension, I have lost all the bundled minutes I am paying for anyway. This makes absolutely no sense. If you pay the back dated fees you should be entitled to everything you have paid for in those fees. When you call the Contact Centre, the agents each time I called gave completely different amounts due, and gave different reasons and stories. There is no consistency to the service and reasoning behind this, and the last agent got heated with me because I caught him out not knowing what he is talking about. I emailed Vodacom Statement enquiries about this weeks ago and no reply to handle the dispute. But I constantly get a growing bill for a service not in existence. Vodacom sucks.
