steeling money from my credit card do not know who they even are

Just received a statement from my husbands credit card company in which it shows a charge of £9.95 has been made to MFI Ancestry.

The only online ancestry company that I signed up to trial was Ancestry.com and this was cancelled before the end of the trial time (i.e.30th October) I received an e-mail from Ancestry.com confirming this has been cancelled and no charges would be made.

Who and where are MFI Ancestry.com and how can I contact them please.
