CANCELLED RAIN BUT STILL DEBITING

In the begining for over a year I had good service with Rain. But this year in the last few months, the signal was extremely bad. I sent tickets on the app with no responses from Rain. I cancelled my account with Rain on the 20th of October. By the next day the internet was cut off and app account was showing in arreas suddenly. I sent another ticket...NO RESPONSES. Today Rain is trying to debit my account, even though I have cancelled and no longer owe any balances to Rain. October was fully paid for and I never even received the full months internet. The whole of october anyway was hardly any signal for anything. So it was a wasted month. Never the less...Rain charges an upfront fee when you sign up with them, you also pay upfront before they activate your account. So Im not sure why they are debiting me when October is paid for already, which was paid end of September. As we pay beforehand for the month ahead. Now they will keep trying to debit my account even though I have cancelled and my bank is keep charging me fees for these unpaid debits. Will rain pay me my bank fees back or what? This is ****************. I never had these kind of issues with my last service provider. Very unhappy with Rain. Even if I wanted to reactivate my account in the future, I will have to now think twice about it. We send tickets and get no responses. Rain needs to stop these debits on their side.
