They never want to cancel subscription

I was a loyal client with rain for about 2 years, i then canceled my subscription on the 1 July 2022 after i was debited twice in June i then sent an email for my subscription to be cancelled, from there i never received any communication from rain instead they billed me in August and September 2022 even though I did not use any of their services, and from my understanding is a month to month subscription and you pay as you use.. One of the agent i spoke to said they cancelled my subscription only in December 2022, i asked why because I have sent communication in July for my subscription to be cancelled. Where they waiting to bill me first then canceled my subscription. They are a bunch of **** and would never advise anyone to use them. They have handed my account ove to nudebt and im not going to leave this matter, i have even started with laying a complain with ombudsman . Even one of my colleagues is having a problem with rain canceling her subscription even though they fetched their router and they are still billing her.
