I am being charged for the service that I don't have

<p>Service consultant contacted me a week ago on the 22 June 2016, regarding a deal for Data, were I will get 6GB of Data for R106 pm x24 months, I did advise the consultant that I'm not always at home so for delivery can my mother sign off the package on my behalf, and they said yes, then I agreed to the deal,my order number is MT- ********** 2-2 . On the day of delivery they phoned me advising me they can't leave the devise to my mother, and I told them to cancel the hole thing because I'm not at home, they phoned me the again for the second time and I specify that they must cancel the hole package as I no longer require their services and they said they will cancel,to my surprise on the 30 June there was a debit order of R39 from them which I think it a pro-rata amount that was deducted to my account,and now the on the 04 July another service consultant phoned me selling another package and when I inquire about the deal they charge me without me having the devise,he said he is not calling me for that and advise me he does not know the number for cancellation of contract,they phone me to take a contract and when I want to inquire about the service they say they dont know the number,I asked for Accounts department they said they dont know it,what kind of the company is this,they are robbing customer because they say they are phoning on behalf of Telkom because I wouldn't have taken it if they did not say they are phoning on behalf of Telkom,They are using Telkom name and I don't know if it Telkom or who</p>
