Rude and incorrect information provided

I took out a new LTE with a smart TV contract in november with telkom mobile. Due to additional charges on my bill. A dispute was logged. While the dispute was being investigated. I was told the debit order will not go off. So I would need to pay the R700 installment to ensure when the query is resolved I would not be in arrears. 2weeks ago I get a letter demanding R800 from me.I called the call centre and wandisa explained to me that is was for November. I did not dispute the charge. I disputed the incorrect information given to me. Now im paying R700pm with no services unable to afford the R800. Threatening to cancel my line. Was I informed exactly what I had to pay in January I wouldve have paid. But all I was told was to pay R700. I got a sms today from telkom to call Mr Van Wyk. I explained to me but all he cared about was the money. Why must I have no service due to incorrect information provided to me by telkom? Im forced to pay my installment with no service. As that R800 in is not my budget. Of the 6contracts I had and have with telkom not once did I avoid paying my bill and this is the thanks I get. Will be in touch soon as im taking this matter to the ombudsman.
