anybody work at radioshack?

i got a new bluetooth headset recently and somethigns not right with it, very bad reception and i want to swap it for a different one to see if it works better. I dont have the receipt or packaging, as i got it from my parents when i was on vacation in florida… will they give me a different one in exchange?

im pretty sure it came from radioshack, they do sell it there.

if not would best buy be a better bet?
