I had an account with Metrofax for several years, and when I went to change providers they absolutely would not port over my fax number. I was disconnected multiple times when I called, they told me I needed a PIN number to port over the number, but they would not give me the PIN. They then told my current provider that my fax number was canceled. It has been exasperating and their customer service was extremely unhelpful as they routinely told me the porting would go through, but it did not. DO NOT WORK WITH THIS COMPANY.
