Domino's Pizza — why should I wait 7 days to get my money for your mistake.

Ordered pizza and 2 chicken wings online. Chicken wings were not available. I asked to provide pizza alone. They refused as it was against to the rules. They asked me to take the alternatives which i don't like and asked to cancel the order. Cancellation will only be processed after seven days, it seems. Why the hell i should wait for 7 days to get back my money for doing nothing. All i did was ordered and cancelled because of your mistake. Why should i wait 7 days for your mistake.
