Horrible Service From Rain -Home Wi-Fi

i want to complain about Rain Home(Wi-Fi), on the 29th Sep 2025 emailed and cancelled the services with rain because i could not afford to pay R619 monthly , Rain send me an email and they reply by informing me that the services has been cancelled , but the 24th October and 1st November-25 money from my bank account was debited without my authorization. 1st November morning ,i send what's up to Rain requesting answers and i was informed by Leila that they deducted money from my account on the 24th oct and 1 Nov-25 for services used and i asked what services use because in October and November-25 i did not get Wi-Fi from you because i already cancelled the Wi-Fi services the 29th September 25 , so which services are they referring to .
