Bestdirectory.co.za

We contacted BESTDIRECTORY.co.za about them listing another business with our Trade registered name. There response is non existent and they simply refuse to acknowledge our legal stand. That in itself, it seams like they just take info of the internet and automatically create users without verifying them. That's not good. My question is, How can you have users on your platform but you are not in contact with them. After numerous emails to them, I'm still waiting for them to remove the copy right infringement from tier platform. BAD APPLES!
