Refusal of site to cancel my free trial

I've tried 5 times to cancel my free trial but the site won't let me. I've also sent an email about it to the site curator but have had no reply. There seems to be enticemendifficultiest for your site to try to make cancellation of the free trial difficult. You take no notice. This is illegal & not the way a legitimate business behaves.
The Police Fraud Section says not to answer any more emails as does the ombudsman.
So Geni site managers cancel my free trial as per my first request on 13th February.
