Formal Complaint

I requested cancellation of my Netstar tracking service in August 2018 and was assisted by a lady called Megan. Megan assured me that she had processed my cancellation effective immediately and that no further debits nor any penalties apply and concluded the call with the following reference number CAS***. The following month i noticed that the Netstar debit order still went off my account and i contacted Netstar, a lady by the name of Pam took my call and i explained that i had cancelled the service already of which she confirmed that she would help to sort the error out. The debit order still continued of which I called in numerous times and spoke to different people. Eventually i was told that Nonzwakazi Motaung is the legal person handling my case and i got hold of her. I asked her to get a recording of my conversation to confirm the discussion between myself and "Megan" where it was confirmed that the service would be cancelled with no further payments/debits due. She was extremely rude and played a short portion of the call where I was only greeted by the switchboard person and was being transferred to a cancellation consultant. After arguing the point that this part of the call had no bearing to my issue she said she has been awaiting the balance of the call from IT and would get back to me. Months had passed with no communication from her. After more calls trying to get hold of her, I was put through to Louisa Hattingh in June this year and was told by her that she is the supervisor and would attend to my issue. She gave me the same story of waiting for the IT division for the call and I explained to her that my complaint stems from August of 2018 and the time frame has just gotten ridiculous she then sent an email to me saying that she has taken it up the line with other staff and will finalise shortly. It has been a month since her last email with no feedback from her and each time i try to call her office line i get her voicemail. Surely after a year someone can make a decision to honour my request as it seems like the call recording is not available after waiting for numerous months.
