I have an Iceland bonus card - it's not a points scheme, you add money to it. I generally round up £1 / £2
Anyway I'd about £60 on it so last time I went in, a month ago used it to pay £35
But saw last week that another £19.50 had come off. I contacted them and said that wasn't my spend and they said they could see it was done 200 miles away and would close my card and send a new one
I asked about the money and they said they would "consider" this once I'd confirmed a new password on my account and my email
I can do that but since my card is on my phone, and no other cards are compromised, I feel they've been hacked, not me
But am not very IT savvy!
