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 ******ies 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.
