Poor delivery service

1st time placing an order and was called by the delivery person to say they cant deliver at my house because they experience robberies we have to meet at a post office . so I explained that I am in the office , decided to change the delivery address to my work place and gave the address. Which they said it will be okay . I get a call from delivery office after 2 days later to say my package returned because they didn't know which building from my work place and I remember mentioning which building while changing the address . Couldn't they call me ? Or go to the reception cause the receptionist would have called me instead of leaving with my package? I am so annoyed with Fastway couriers with the service received.
