Some printer cartridge wholesaler wanting to talk to us about purchasing.

Constantly calls, has left a number of 800-965-1180 (with an extension) for us to call back on.

They don't seem to take no for an answer and continue to call but at least they are American so you can understand what they're saying.  Same o'l BS as the foreign telemarketers but they should at least remove you from the list when you ask them to.  They have no excuse.
