****ed up company

So on on the 28 Nov 2025 Rain deducted R3000 on my bank account without authorization.The normal deduction date is the 1st of every month.I lodge a complaint and they **** here on Hello Peter that they will contact me.Until to day I have not received ay feedback from these ****mers.On the 30 November 2025 I requested for my subscription to be cancelled.I was promised that I was going to be assisted with cancellation,after chatting to their chatbot named Sam and Laila that keep repeating themselves.On the 1 November 2025 they sent me a payment reminder SMS,I asked for the feedback regarding my initial complaint.They said that a refund takes between 7 and 10 working day.To my surprise my subscription was disconnected on the 3rd due to no payment.I tried to make an arrangement,they said that my Promised to pay was up to date.Mind you I work from home and its important that I have wifi network.Do I have to take legal action or what is it that I have to do.Cos when I want to cancel no one is assosting me and when I want to make arrangements,no one want to assist me.Kanti what the **** do I need to do?????
