Shocking Administration - Forced to make payment and refusal to cancel membership

I joined InterNations about a year ago to market my business after I became retrenched because of poor economic circumstances. Earlier this year I emailed InterNations to ask for the cancellation of my membership but instead of assisting me they emailed me diverse threats to make a payment of $59.40. After receiving different threatening emails from their finance person, I explained I was not aware of the online cancellation and I am not interested in proceeding with the membership. They informed me I must please cancel the membership online, but because the system blocked me, I could not follow the cancellation process. I subsequently informed them I am unemployed and cannot afford the membership. They threatened me again by handing me over to a debt collection party. I am therefore being forced as an unemployed person who requested a cancellation to make payment to a body that provides no service to me at all.
