Now they want to sue me

After refunding me, Abbey Carpet Corner is threatening to sue me.  They’re saying I cost them business… isn’t that what all bad reviews do?  Isn’t that even the point of a bad review?  I know they’re trying to bully me, but Neela is freaking out.

I’m on the fence.  I got my refund, so I don’t personally need the site anymore.  However, others will continue to end up getting screwed by these guys if they don’t know about my experience.  Anyone out there with some advice?
