They are in India.  7 years ago I had a contact for them but that number stopped working.  It took months to get paid.  They do not respond to e-mails, they provided no contact for questions on orders, follow-up or payment.  I refuse to work for them due to these issues. 

They send orders, I tell them to re-assign them and remove be from their vendor list.   Then they send status e-mails.  No one will respond to them when I tell them to re-assign the orders.  Then they cancel due to no response from me.  I'm not sure what happened to them,  They used to be a good client.

Good luck getting paid.
