How frustrating, I'm having the same problem, I had a pet boutique email me and state..."these feeders are not selling, I think I have to return them". Question, I know the customer is always right, but how is this my problem? I emailed her back and told her that if the problem was a defective feeder I would gladly exchange it for her as soon as she sent the defective feeders back. Still waiting on a response. Did I handle this okay?
