Vodacom refusing to adress their consultants incompetance

Last year I no longer wished to renew my contract with Vodacom. I went into the Vodacom store at Gateway KZN inquiring when I was to notify Vodacom to cancel my subscription. The consultant gave me a number to call, which I did. The online consultant confirmed my account will be no longer as of the 1 December 2018. Come the 1st December I notice my number is still active, on Monday the 3rd December I went into the Gateway store to report my number as still being active. The consultant called the cancellation department, I explained to the gentlemen that I had notified Vodacom in due time which is how I knew this account should not be open and the reason I am in store reporting it. He noted this query by immediately cancelling the account and informed me he was put a note to the accounts department to NOT bill me for the month of December 2018. Days later I received an invoice form Vodacom billing my for a month’s subscription. I called the Vodacom call centre numerous times, spoke to numerous *********** persons who could not and have no resolved my query. NO ONE AT VODACOM KNOWS HOW TO RESOLVE THIS!!!! A consultant told me to issue a STOP ORDER at my bank to ensure no debit order will go off as he was not confident this will be resolved in time. A debit order did go off which I reversed and was charged a stop order fee. Vodacom wants me to tell them the exact date and time I called to cancel my subscription. I have asked them to forward my itemised call logs for the months July, August and September as I called from the cell number. THEY REFUSE TO SEND THIS TO ME! Stating they no longer have access to my account as I am now on pre-paid. I don’t believe this to be a justified reason as if you can send me invoices for those months, you can send me the build-up of that invoice. I have been trying to resolve this since the 3rd December 2018. No one form Vodacom is addressing this. The following are my ref numbers 1- ********** ********** , 1- ********** ********** ; 1- ********** ********** ; 1- ********** ********** . All I get is a text message 2 days later informing me my query has been resolved when nothing has been done by Vodacom! This morning I received another invoice from Vodacom, for the amount they cannot justify I owe them plus R100 when I have no contract with Vodacom since December! I am willing to pay for the remaining charges for November 2018 that I incurred. I am not willing to pay for December 2018 subscription or any further charges as there is no contact with Vodacom. Vodacom is also to reimburse me for the stop orders I have had to put in place as instructed by their consultant. Vodacom, will someone competent please get in touch to resolve this. This is a result of your consultant not doing their job properly the first time which has left me painfully having to deal with this.
