Swiggy — order not fulfilled

Ordered a four seasons pizza and paid for it.
The delivery guy called and said his tyre had a puncture.
Called swiggy customer care.
Not much help. Asked to cancel order as they could not fulfil.
The payment would be credited within 4-7 days.
Why do they take orders that they cannot
Pathetic customer service!
Thanks for wasting my time and friday night swiggy!
