Rain deducted money from my account without my permission.

I deactivated my rain in February 2021, due to no signal in my area with the tower down on a constant basis. I communicated via phone calls and emails and gave instructions via email to stop the service. I was then not billed again and did not use the sim at all. Then in September 2021 all of the sudden a payment was deducted from my bank account. When I checked on the app it was an arrears amount due. I phoned in and asked to get a refund, but was told its for January payment, however, I was never able to even use rain and was under the impression that the service has been stopped. Then nothing happened again until Des 2021 when a strange amount was deducted from my bank account from Rain and then again in January. I will be opening a formal ***** case against Rain at my bank hoping it will work for unauthorized deductions from my bank account if the total of R1080,61 is broken down as follow: R479(Jan2022) +R123,61(Dec2021) +R478(Sept2021) I asked for it to be paid back by 20-02-2022. I have not received a promised phone call from a manager to discuss this further only a link to cancel again and once I follow the link there is NO way to cancel the service same as last year and emailing and phone calls are completely useless!! I will have to take all necessary steps to get my money back as I am currently without a job and cannot afford to have money ****** from me for something I cannot even use and do not want!! Please if anyone has a way for me to get my money back, please help.
