Empty promise & indifference

The 1 star I'm giving them is because there was a time when my parcel came on time. A parcel was sent to me on Wednesday, 9 October for delivery within 2-3 working days. I check with the sender on Monday, 14 October and she checks with Postnet who confirms the parcel was received. On Thursday, 16 October I go to Postnet and I am told they could have had a wrong contact number if i did not receive any communication. I tell them the contact number is correct, according to the Way Bill i got from the sender. It turns out the parcel was received and put away without processing.

What was appalling was the response i got from the assistant. On asking why do they promise 2-3 working days delivery and yet don't fulfill that promise, she responded by saying "but you don't pay any extra for it" and didn't seem bothered by the mishap. This is the 2nd time a parcel is not delivered on time.
