Thanks for bringing this to our attention. I have informed my colleague who's in-charge with our directory listings to do a follow-up on this supplier. She will try to get in touch with them and she has temporarily removed them from our directory pending further investigation.
In the meantime , I think what you did (pulling off your listings and putting your other store on hold) is the most appropriate thing to do right now until we hear from them.
Again, thanks and all the best :)
