In that case, I'd be contacting the source with a complaint. Is there a warranty? Personally, I don't think I'd want a replacement, but my money back to buy a different one altogether. But that's your call.
How "new" is brand new? Did you test it for a week before moving your snake in? That's always recommended- some things just aren't made as well as they should be & you want to find out before your snake does.
