While you work in shipping and receiving, I work in customer service. Their response, or lack thereof, is unacceptable. Even if they don't know the answer, respond with "I don't know". While that answer sucks, it's better than " ".
Thought I covered that in the Damage control - Not so good.
Like I said, I truly hope they get all this sorted out SOON. It sux for all - Us and Them.
By the way, the more information you have received is actually more speculation until your specific issue/order is handled.
For all anyone knows it could be on a Pallet load of packages waiting to be sorted out at fasttech or in a 60,000ft warehouse at Customs awaiting release. Only time will tell.
As to CS (25 yrs retail) The appropriate response is - let me look into that and I'll get back to you.
An <I don't know> answer generally gives the customer the feeling you are clueless and not going to be helpful.
