Cell C- Customer care & follow up Pathetic

I've been struggling since 22 December 2022 to cancel my son's cell phone contract with cell C. The contract came to an end of its lifespan and was according to what I was told now a month-to-month contract. My request was initially to cancel the airtime, data & SMS’s and just use the number as a pre-paid number. I sent an initial email requesting cancellation. Cell C rep**** and acknowledged receipt of the cancellation request and that it has been forwarded to the cancellation department and that I will be contacted shortly. Early January I sent an e-mail again stating that I have not been contacted yet. Every month I had to reverse the debit order. When they do contact me, they just say they logged a call and that someone will contact me. After numerus times where I even phoned them, I had no assistance telephonically. On 19 May 2023 on my way to my mom in hospital I stopped at the East Rand mall and went to the Cell C shop. Hoping that I'll get better assistance face-to-face. At the Cell C shop, I showed the guy assisting me the e-mails stating acknowledgement of my cancellation. He calls Cell C and a lady assisting me tells me that they have been trying to get hold of me and on the dates & times she tells me they phoned I have no missed calls or SMS’s on my call register. She then tells me the cancellation department will need to confirm some of my details and that they will call me shortly... They call me while I'm driving, and I ask the agent to please call me back a little later when I'm at the hospital upon which the agent agrees. Then no contact again on that day. A few days later they call and I get to speak to the cancellation department and they are able to confirm my details. But the operator tells me I need to pay the outstanding amount. I then explain that I have done my due diligence and already cancelled the contract in December & gave them notice. And that Cell C acknowledged receipt of the cancellation. The agent then tells me the collections department will contact me. And once again radio silence. I have the Truecaller app on my phone and ever since I've been answering all SPAM calls hoping that it is Cell C willing to assist me. This morning I get a call from MBD attorneys telling me my Cell C has been handed over! This is pathetic. There were numerous times where Cell C phoned my husband on his number and he tells them to call me, gives them my number & then contacts me to tell me Cell C is going to contact me again. But nobody phones. He has even gone as far as to telling them to contact me while he is on the phone but they still don’t contact me. As the customer I did what was expected of me to cancel this contract. Cell C then handed me over to MBD Attorneys for the outstanding amount of a contract that alraedy expired more than a year ago.
