Our business has done work for CHW for over a year. All of a sudden they stopped paying their invoices and gave us a run-around about having to fill out duplicate vendor forms and submitting our invoices through email. I've emailed the company 5 times and every time the mailboxes are full. I call EVERYDAY and haven't been able to talk to a live person in over a month. They weren't great to work with and would argue over EVERY job that needed approval but since they aren't paying or replying at all we will no longer do business with them. We recommend NEVER using this company. read full review »
