The unlimited being Avoiding when you want to cancel with them

They approached me at work and ******* me into approving their deal , I told their agent that I was not ready to join them but the guy told me to contact them should I change my mind but I never did because I knew I was too broke to sign up . They unexpectedly deducted my Money, when I told their agent I would like to cancel , he was arrogant and told me about how I cannot cancel or stop a debit order . They are always unreachable, one thing they will do is to hang up my calls .
