Unable to complete my cancelation in order to restore my credit rating

I moved out of my new place on the 31st of May. On the 3rd of May I called spoke an agent about moving out and the agent said that I must request for a cancelation which i did. I then called again to get an updated about the request. I then spoked to a different agent who told me that what i did was incorrect and i should have requested for a relocation . I then canceled the cancelation and requested a relocation. I called to get an update of the relocation were i also should to another agents agents told ne that I was actually supposed to do I cancelation. I actually explained to him that I initially did the cancelation but I spoke to an agent who told me to cancel and cancelation and apply for a relocation. He said that I must not pay for June because I have paid my installments gor April and May and he transfered my case to legal department. Early this month I had a email saying that the cancelation was canceled. I do not why because that agent told me that we transferred my case and my account will be cancelation. And I will receive a paid up letter. I went to the bank today and checked my credit score send found out that Vodacom has attempted a debit order on my account. I am not happy because this is damaging my credit record. Can Vodacom enable call transfer within agents because it is pointless to contact different agents and having to explain one case to different agents. I been calling Vodacom and trying to get hold of this agent, the other agents promised to contact this agent so I can solve my case. Till now they promised to call I am still waiting. The way you treat your clients its not ok. Remember we made you one of the biggest telecommunication companies.
