I had the same experience as the poster above, but didn't notice until SpeedDater had deducted £48 from my credit card. I was shocked to discover they had been charging me without my knowledge.
When I phoned to request a refund, the customer service agent was less than helpful. I explained that if you sign up to buy a ticket for an event, you do not expect to end up subscribed to a website by default. It may be somewhere in the small print, but this is an extremely underhand tactic and if not illegal, is certainly immoral.
Needless to say, I will never again attend a speeddater event. (I am still waiting to hear if they will refund my money.)
Pros
None
Cons
They are con artists.
