But have you actually checked whether the points have appeared on your Tesco account?
I did this a couple of years back with Skybet and William Hill when I could load £500 into my betting account by Tesco Visa and then withdraw the next day to my bank account. Soon closed by the online betting people by restricting bank refunds only to customers using debit cards to load accounts.
I also seem to remember a Tescp Credit Card T&C stating that online betting was treated as a cash advance (albeit without fee).
