Line blocked yet billed monthly

In December of 2015, my two lines *** & ***) were blocked for the balance of R600 & odd rands that I was owing. To my surprise, the bill is currently showing an amount I do not know about which is way beyond my apprehension. 1). You continue to present a debit order in my account, despite knowing that you have cut your services & this has caused me harm in my bank account. 2). Data bundle contract renewal was never okayed with me after its expiry date, but was simply renewed & this I was okay with for as long as I was still working, but now that I am no longer working, It serves no purpose for me at all. 3). I want initial balance owing to be corrected less the additional monies after blockage date. 4). Cancel the contracts so I can arrange for the payment of the R600+ amount I originally owe you for the reinstatement of my lines and stop presenting the debit order into my account as I no longer get service for it.
