BILLED FOR SERVICES NEVER USED

I signed up for their service and received a sim card the very next day before me even approving, i thought this was great service. I received a sim and it was never activated because i had issues with it...so i have NEVER EVER used their services and have sent emails and filled out cancellation papers for a service i never ever used...Home close has been billing me every single month religiously even though i have NEVER EVER used their services. I cant call them because no one ever answers and i am not getting any help from them they keep asking me to fill out forms i filled out last year already, on Facebook there are many other people who have experienced the same. Surely it should be ******* to bill customers for services never used...for a sim that was never ever activated even aft cancellation information g=has been sent a million time over...i have been handed over to debt collectors by HOME CLOUD for something I've never ever used...this cant be right!
