Rain Internet service provider is a NO NO NO

cancelling this service is a nightmare ,i cancelled on the dashboard as they say you should over the phone ,i receive a ticket number 08 October 2020 they told me it will take 1 months notice ,which i agreed 02 November i am billed which was fine,on the 23 November 2020 i phoned again this sim card was not cancelled ,and the guy says i must wait another month ,1 month from 8th October is 08 November ,we are in December 2020 i got debited again ,what a pathetic service provider do not use (Samone chester the consultant was nice she understood and also doesnt understand why this happend to me )she escalated the problem and said someone will get back to me in 24-72 hours ,lets see what happens(my advice to anyone do not take out rain
