Buying a headset for my boyfriend for Christmas for £24.99.

Order went through okay, and i got a confirmation e-mail.
Then a few days later AFTER taking my money, the customer service lady named "Fran" told me there may be a problem with the order, and kept asking for my card details and house address, also my previous address.
I told her, before reading the comments on this website. Completely regret it.
They've taken the money for the headset and are refusing too send me the headset.
Only 24.99, but to me that is a lot of money..
