Off-topic Q. I've applied for CL Final tickets but I want to withdraw my application. I've emailed the ticketing people and they said the deadline for withdrawal has passed and the only way I can get out of it is if the payment doesn't go through. I've used a credit card so how can I prevent any payment from going through? (This is still at the ballot stage so there is no guarantee I will be allocated tickets).
Could I tell the bank to block any payment to UEFA? I can't cancel the card. Any ideas appreciated.
