I ordered a pizza from Pizza Hut in December and have found out today that a company affiliated with Pizza Hut has been taking £10 out of my account each month from the account details I entered into the Pizza Hut website. The company is called Shopper Discounts and the name SHOPPERDISCOUNTS.C has appeared in the bank statements. I have never heard of this company nor have I visited their website before. I would check your accounts if you have ever ordered from Pizza Hut and used card details.
The number to phone to demand a refund and remove your details from their database is: 0808 234 1539
Hope this is useful to someone.
