They have to make it clear that it is a trial and you only have 14 days to return goods or you will be charged. There are a lot more conditions in the Act, so suggest you read it in full to see if you can find something that applies to your situation. There is a section that refers to being surveyed I believe and they should give you terms and conditions at that time, not expect you to read them up later after you have signed. (What if you didn't have a computer for instance?!!) If you search for "The consumer Contracts Regulations 2013" you should be able to find the Act in full. It takes a lot of reading but it is worth it if it stops companies ripping you off.

I found the same thing, no address, so I used email. The act is very clear - they are in breach if they don't give you a return address and if they don't give you their terms & conditions in a durable form (that means not just popping up on the screen) and they should be given before you purchase, if you were caught in Sainsbury's they no doubt didn't give you a written terms to read before you accepted. Companies who breach this act risk imprisonment, so you can be strong in your complaint. Good luck!

Hi, I got caught by an online pop-up offer of a choice of 3 gifts (one of which was Stemologica for postage only). 2 weeks later they took a further 97.95 from my account! On complaining they claimed it was a free trial but offered a third and then half my money back. I persevered with advice from Trading Standards/Citizen's Advice and quoted the Consumer Protection act 2013, which came into force June 2014, whereby they had failed to provide a durable form of terms and conditions and also a return address - they paid up in full immediately. This Act protects everyone if you were on a free trial or a free gift and they fail to comply by providing a clear copy of their terms as above. Don't give up, my bank fraud department suggested I accept the 50% offered - thankfully I ignored their advice!
