Failed Customer Service

I have been trying to cancel my contract for a couple of weeks now, all the operators ends the call, after they hear that I want to cancel. I have paid the early termination fee, which is now being used to pay for the subscription that I am still being billed for. Thus far I have spoken to 8 agents. VIA email, the phone and via Facebook. This is the response I've been receiving for the last month: we humbly apologize for the delay in resolving your query. Please note that we are following up with Retentions. ~NK. Is there someone that can assist me or is this a **** to keep clients tied to their contract?
