What and when is a unpicked up return considered abandoned?

[Libram]

I have two tvs bought through a seller on Amazon sitting in my house, they both were replacements for a defective tv. Both tvs were supposed to be picked up by the same seller as returns. It's been about a month and a few emails of me asking when they will be picked up and I still haven't heard when to expect a shipping company to be by to do a pickup. When do these tvs become considered abandoned by the seller? I let Amazon know I wanted a refund after the seller dragged their feet on doing a return, I also let them know I have the tvs and Amazon themselves accepted my claim and refunded me on the original tv.

What is the name of your state (only U.S. law)? Washington

They should be picked up by the seller if specified. Usually you are responsible to pay for returns.
