I only use couriers who have common sense. I once ordered 2 x T-shirts from the UK, but the SG deliveryman could not locate my condo as the online store wrote the wrong postal code as well as the incorrect mobile number even though this was not my first order from them. That courier promptly sent my parcel back to the UK, and refused to even deliver it to my correct address (while it was still in S'pore) after I contacted the courier because it was "official policy" to return the package to the sender if they wrote down incorrect delivery details. WTF!
