I requested the free trial sample of anti-aging serum product which i paid postage of £1.93 for . This week i have now had an authorised amount of £87.41 pound taken from my bank account. I have received and accepted the trial product but I have not requested any further supply of this prooduct so how can they just go ahead any take money from my account without my consent??? Have I been duped into this by accepting the trial product?? It certainly was not clear that this was the case and I certainly would not have requested the free trial product if I had known that this was going to occur. What recourse is open to me to get a refund???
