ID says not provided. They have called every hour on the hour three times this morning. Ring full amount of time and answering machine kicks on and message left is "Thank you. We will call back at another time." Message sounds electronic. I would think if it were a legitimate call, they would leave a better message or quit calling every hour on the hour.

They called first thing in the morning and left a message from "Office Depot" about my order that was on hold had been canceled, and I needed to call their customer service back at 1-800-463-3768 which it is indeed an Office Depot number, they told me they usually hire West Interactive (a customer service specialized company) to handle customer service calls in their behalf.

I believe there are other companies doing the same as Office Depot, that's why West Interactive keep showing in the caller ID.
