Disgusting service

Been a loyal rain customer for a few years now- and the service I have received this week very disappointing- so I’m on maternity leave and can not afford the service at the moment. Hence I requested a cancellation but nobody got back to me - my account was debited on the 25th - so my sim was active but not connected- so now I’m being billed the full amount and it was disconnected very disgusted with the way I’m being treated very disappointed and the sales rep has a nerve to give me attitude.
