Findmypast subscription 11 January at 9:57AM edited 11 January at 10:22AM in Consumer rights

On the 6/1/23 I received an email offering a 14 day free trial with findmypast.
On the 7/1/23 I started looking at the website, I mistakenly subscribed at 19.03 and immediately cancelled. I have an email confirming my subscription at 19.03 and an email cancelling my subscription at 19.03 from find my past.
However I have been charged on my PayPal account £199.99 (1 year subscription) 
I know it is my mistake, but had no idea I would be charged, and assumed I had a 14 day free trial and could cancel my subscription within that time and not be charged.
I have contacted findmypast and have been offered a reduction to a 3month subscription at £50 with a refund of the difference.
Am I entitled to a full refund?
Kindest regards
Cathy
