My debit card expires at the end of the month so had a reminder text from Smarty to update my payment method. The new card's number is the same, just a new expiry date and CVV number.
When I go into my account and select the option to add a new payment method, I enter my new card details but Smarty then goes on to charge me £6 (my monthly plan amount). It's not due for another few weeks though, so why is it doing this?
Do I even need to update my card details at all given that the number is the same on the new card?
