Vodacom incorrect billing

I would like to complain regarding the poor service I have received from Vodacom to date. In February I was given the 1 month free Vodacom LTE trial and the router was delivered. I was away on holiday at the time of delivery and I only used the router and plugged in from 13 February 2021. The following week on the 22 February 2021 I then received and email from Vodacom saying that would like to install my Fibre. I then rep**** saying I had not requested any Fibre to be installed and they were to cancel everything immediately. I then received an email to say everything had been canceled. I also switched off the router and put it back in the box for collection from Vodacom which still hasn't happened. I am now being billed for R942 for Fibre that hasn't even been installed at my premises as I currently have Fibre with a other company and for a free month trial of LTE. I have called in on 2 March 2021 to sort out this issue as they are billing me for a free service I was told that within 48 to 72 hours my ticket would be assigned to someone to assist me with my query. On 5 March 2021 a consultant Bulela then called me, (who I dealt with on 2 March) saying that she can see no one has been assigned to my ticket yet and she will escalate the issue again and also told me that there is a backlog of cancelations and the cancelation can take up to 30 days which is not my problem. This is very stressful for me as my debit comes off on the 15th of the month and I wanted this issue resolved before then. On 8 March 2021 I called in again and Tashreeq Keraan then told me there is some one assigned but they haven't yet resolved my query. He then said if I have had no response in 48 hours I should email him to his personal email. I then emailed him twice and still have had no response and no communication from Vodacom. Today I received an email stating that my Fibre will canceled as of 1 April 2021, but I don't even have Fibre installed at my premises with Vodacom.

The initial sales person Marissa who sold us the free month trial told me this is not her problem and that the issue is within Vodacom and she cannot help me but offered to pay R600 for the debit that is coming off. I then refused for her to pay money to me as this seemed *****.

First off Vodacom promised to sort out my query and they have not within the given time frame. Secondly on the forms I filled in for the free month I never filled in account or banking details as I was told that it was a free month and that it was not required so how can you run a debit order for an amount I have not authorized. Thirdly you are making me run after you for a mistake which is your own and stressing me out as I have a young child who is currently sick and I obviously need my money every month and cannot afford to be paying the debit order of R1250 which is set to come off on the 15th. I am really appauled at the service and as soon as my contract has lapsed I am definitely going to be canceling my existing contract with Vodacom.
