I ordered a trial of Prolash and I cancelled 11 days after ordering it, (well within the time limit) using their required method on their website, an email headed Returns Request.
They replied saying that they will cancel any further supplies but to carry on using the stuff. I wondered why they didn't ask me to return it but I thought that with H&S issues they wouldn't be able to sell it again and would have to throw it away so maybe this is a way of me changing my mind with further use.
I few days later I noticed they had taken £67 from my account.!
I am now locked in dispute with them. They said I didn't tell them I want to return it. The Header clearly stated 'Returns Request' so how much clearer could that be..?
I think their marketing is sharp practice and I'm sure it's altogether legal.
Don't bother with the 'free trial' - it won't be free...!
