Let me OUT!!

Despite cancelling my month to month UNLIMITED internet deal a month before my move I am still being invoiced - and charged interest for a service that should have been disconnected. Hours of calls to the call center, online cancellation and facebook messaging - useless. I'm paying double for internet now and was told it would be temporary until fiber arrives. Accidental double payment on my LTE account doesn't reflect. They did not explain the LTE contract and now I am tied to a 24month deal?! I WANT OUT. Internet should not be a prison sentence!!!
