Rain Cancelation

I very disappointed in Rain I never had any problems with them before I have been a customer for many years and I've already sent in a complaint on the 23rd of May Rain responded to that complaint and said they would contact me but I still haven't heard from them up until now with regards to a cancelation request I was involved in a car accident a few months ago and haven't been working since I do no have any sources of income at the moment as I'm still not fit to work I can not make payment arrangements and yet they keep debiting my account which is empty and in a minus because of insufficient funds due to debit orders from Rain being unsuccessful they refuse to collect the router and cancel the subscription and yet I have not been using wifi since April when I sent in the first request to cancel
