So I'm thinking it was a wrong number?

Setting: the bookstore where I work, 3:36pm

The phone rings.

Me: "Hello! R&M Bookstore!" 

Caller: "..." 

Me: "Hello?" 

Caller: "You speak Russian?" 

Me: "Um..no...I'm sorry." 

Russian Lady: "You have translator?" 

Me: "Um..no. We're a bookstore." 

Russian Lady: "Oh, ok..." 

Lengthy pause. I debate my options.

Me: "Can I...help you find a book?" 

Russian Lady: "No!" 

Me: "..."

Russian Lady: "Ok, I go back now."

Me: "Ok! Well...bye then!" 

Russian Lady: "Bye!"
