I am going through a tough time at the moment and idiotically fell for a gift card scam. Someone hacked a friend's email and got me to buy a £100 card for a tech company whose products I don't use. Fortunately I came to my senses before doing what they wanted me to to activate it, but now I am left with a card I don't want. The third party retailer I bought it from won't refund it and my credit card company aren't interested as the scammer didn't actually get the benefit. Short of trying to find someone who will buy it off me is there anything I can do?
