Terrible customer service and lying consultants

I received an e-mail from RAM couriers on the 1st of August informing me that a parcel will be delivered to me soon. I contacted the customer care service informing them that I will not be at the delivery address on the 2nd and 3rd of August. I was told that it was fine, the parcel will be delivered after the 3rd. On the 3rd of August I received a phone from one of the RAM consultants informing me that they have tried to deliver the parcel. However, the driver could not get hold of me. I informed the consultant that the driver never contacted me. The parcel was meant to be delivered at my work place and a receptionist confirmed that no one came to deliver something for me.. Today I made a follow up and I was told that the parcel was returned to the sender. You will never make customers smile with such disgusting service and lying employees.
