Unauthorised Debit Order

I “cancelled” my service with Rain at the end of November 2024 already and have NOT used the router at all because I relocated. I have sent messages via the Rain App, via e-mail (which never ever works) and also via Whatsapp, reminding them of my CANCELLATION and to collect their router from my new address. I have proof of this communication! Rain decided to just debit my bank account, for the amount of R595 for January 2025, WITHOUT AUTHORIZATION or without even acknowledging my CANCELLATION REQUEST for over a month now! This is *****! I WANT A REFUND, of my hard earned money, immediately! I have submitted a cancellation in advance, which Rain has intentionally ignored and now quick to debit my account without permission! I will not pay for a service I have not used in a long time now, which I’m sure Rain has record of. I WANT MY MONEY BACK! Worst service provider ever! The useless app doesn’t even allow me to delete my banking details, which means that Rain will continue to, *******ly, debit my bank account whenever they feel like?!!!
