London Marathon Expo purchase, duplicate payment

Jo PoweredbyChocolate

Not really sure where to post this but I'm sure I read somewhere someone else it happened to, got my bank statement today and The Marathon Store has taken a duplicate payment from me

I've emailed and phoned them, they've taken my card number and are looking into it ( I emailed them my bank statement as proof )

I'm sure I read this happened to someone else at Expo, not sure if it was at the same store

Ring any bells?
