Debt my account without consent

I kept receiving calls from Nudebt about my account from Telkom, I informed them my account is up to date and therefore since telkom contacted them, yhey need to contact them again regarding the matter. I called Telkom and the lady at Telkom told me I must ignore is an error. They sent sms, non stop. 23 Oct 2015 they debited mu account, while Telkom debits, when I called they say I must go reverse it at the bank or call Telkom for refund, Telkom says I must call Nudebt, they are taking me from Pillar to post, what about my money that I have to use to go to work and second what about my record when I reverse, I need this company to pay for the charges that incurred in my account when I reversed this debit order because they did not intend to refund me.
