Nobroker — Packers and movers

I had scheduled for packers and movers for this Saturday 29th April and got a call from Nobrokers team confirming all the details and informing on insurance scheme on the electronic and after all this they informed me that the slot I had booked is not available now and want me to reschedule to 2 days after. I informed them that they can't come and inform me at the last moment because had so many bookings and services planned based on this movement. This unprofessional behaviour is not expected from Nobrokers.
