I too "fell" for this. Availed of the €5 trial back in April and obviously missed the small print where it stated about the auto-upgrade to Premium at €179.94 30 days later. Stupidly, I didn't notice that transaction on my account (although, from reading other people's experiences here, even if I had known about the cancellation period and tried to cancel, they probably still would have taken the payment out). Unfortunately, I paid them with a debit card initially so I don't know if these carry the same protection as credit cards.
Anyway, I wasn't aware that that €179.94 had come out of my account until last week I DID notice a payment of €179.94.... ANOTHER payment. I contacted my bank who told me it was Be2 dating site. That's when I checked back and discovered the April deduction. Obviously I contacted Be2 straight away who have refused to refund. Strictly speaking, because I didn't see the auto-renewal (or the exorbitant amount) in their T&Cs I can't really see where I have a leg to stand on. That aside, I told them I wanted to cancel and they asked me for information such as username, password, email address etc which I gave them (I would have questioned why they needed this info as surely they already have it but at that stage I was desperate to cancel the account). I then asked them to acknowledge my cancellation. They haven't done. What they are now doing is saying that unless I pay $180 US dollars by Western Union(!) to them to cancel my account (!) that the deductions will continue.
This is a new tactic as far as I can see but whilst my communication with them has been professional and polite to a point, I did use some choice language yesterday. Fcuk em. They are total scum. I need to cancel my debit card, try open a dispute with Retail Service Disputes at my bank and see if I can get any money back. I am going to ignore them from now on as I can't see them being successful in persuing this and as someone else pointed out, they don't have a home address to direct debt collectors to.
I'm based in Ireland and if anyone is planning to take this down the legal route - I'm with you. When I have time, I'll be reporting them to all relevant bodies but for now, I need to clear my head of them.
