Rain Network issues and bogus cancellation process

I've been trying to cancel service now for 4 months, the 5G network is wack hence my cancellation, but that's nothing compared to the client service portal. i logged 4 tickets to no reply, i tried pausing payment but because for some reason its under 500 i'm unable to stop the debit. Now this is my last resort to try quit this ill relationship i have with Rain. Somebody help!!!
