Frustrated - Bank account debited, threatened with final demand for a cancelled contract

I don't know if I should say I'm frustrated/lost hope/disappointed

I initially reported that my bank account was continuously charged and received final demand for a contract that I had cancelled/did not extend with Vodacom. When there were no funds in my account I made deposits to avoid being blacklisted as I was threaten with a final demand letter, this is for a contract that was supposed to be closed/cancelled end of Jan 2023 as I had requested. I was eventually given a call by Vodacom around November and notified that I would be reimbursed for all the money obtained post the point of cancellation but to this day, no feedback/phone call post the email notifying me that my number will be converted to prepaid - I don't care for that, I want my money back. I don't want anything to do with this Vodacom number anymore. This was an error done by the agent that was supposed to be helping me but now I am paying for her mistake, how is that possible? This is so unfair, I regret signing up for this contract and I have been patient in all this, I have now resorted to report this on Hellopeter, the same escalation will be done to Shameel level, I have been patient for far too long, it's enough now.
