I've suffered of UPS twice within a month, but similarly with earlier cases it has been the same hassle, uncertainty, stress and failed deliveries.
We live in a condo building and are both working so UPS is a very inconvenient delivery method for us. 1) We need to arrange a work-from-home day to be available when the delivery comes, 2) most of the time the courier doesn't even bother to use the buzzer and reports a failed delivery attempt. So even if we're at home we will miss the delivery.
My latest experiences:
1) Two weeks ago I was waiting a delivery from Costco. Twice UPS attempted to deliver but failed ("The customer was not available..."). Then I called and magically the delivery was successful in the following day. We live in a condo building and have the buzzer connected to cellphone. UPS customer service confirmed that they have right address and buzzer code in the delivery.
2) Similar case happened today with another delivery. This time the excuse was "The receiver is not listed on the building directory." I called the customer service and was told that they have the right address and buzzer code. Another attempt tomorrow. *sigh*
I only wish all companies would use Canada Post. With them I can always pick up the delivery from a conveniently located Post Office. Using UPS is a huge downside for any online Store.
