Need someone to repair pump in pond with golfish

Morning everyone,
I got up this morning to find that the pump in the pond in the garden is broken. The water level is really low and the goldfish are really struggling!!

Any advice? Who do I call to fix the pump? Would it be okay to put bottled water in the pond in the meantime or shoudl I transfer them to a bucket or seomething?

Ask a pet shop or aquarium supplier.
