Nonexistant support, incompetent staff Our experience with Sfax has been nothing but frustrating. E-mails to support on simple issues go unanswered. We tried to port our numbers over, but after 4 months the porting department seems to be unable to enter a port request properly even after being provided with a CSR from our current carrier. When we checked with our current carrier's port-out department, it looks like only half of the port requests are making it to them. We ported our voice numbers to a different vendor just before attempting to port our fax numbers and everything went fine. I'd recommend avoiding sfax or any j2 brand.

Will bill you regardless of canceling Faxes did send. My issue is with billing. I canceled by end of trial date. I never got a confirmation so I emailed 3 additional times and left 2 voicemails. Unsurprisingly I received a $29.00 bill. I do not recommend.

So far so good We have been using sFax for a number of months now. It's working well except we are having a bit of trouble porting existing numbers which seems to take up to 2 weeks.

Terrible They have no tech support. No one answers the phone or responds to emails. Unable to renew our account online so now my account is locked. They now have our fax numbers hostage. User interface is form the 90s. Stay Away from this company.

Number wouldn't port. We couldn't port our existing fax number. We liked the software, but it wasn't worth the amount of work that would go into changing the fax number everywhere for a doctor's office, nor did we want to pay for two services so that we could forward our number.
