I am in need of some advice. I recently purchased a cattleya plant off eBay and unfortunately, it arrived with both scale and mealy bugs all over it. I have ordered lots of plants from eBay before, but never from this seller. I've never received an infested plant before. I'm wondering if it is appropriate to ask for a refund, or should I just leave negative feedback. I get the feeling that the seller was just unaware of the bugs, rather than intentionally selling me a bad plant. What's the protocol here?
