Not as effective receiving faxes as a traditional machine. We are unable to receive all faxes. 5% of income faxes are never received and we have to direct people to fax to our back office fax line Update: I have tried multiple times to have this issue resolved through support. I am told the person sending the fax has a problem with their phone line. but yet they can fax to my back office fax no problem. Tell me how that makes sense?

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.

I was a customer from 2016 to 2024 I was a customer from 2016 to 2024. Billing issue when my bank placed Sfax on a list of potential threats. Before it was discovered, difficulties ensued. Unfortunately multiple emails to billing, tech support, and customer service yielded zero response. Left two voicemails. Never heard back. My fax did not work and I could not get through once locked out. It wasn’t about money or payment, it became a tale of avoidant customer service and neglect. I submitted a ticket to end services with my feedback attached, heard nothing. Received a canned email that my complaint was received and I would hear back in 48 hours. Week/s later it’s a second email that it’s cancelled. Truly one star as no amount of faxing interface would make this acceptable. I was never actually acknowledged.

Impossible to get any customer service. They never answer their emails or phone calls. I have tried to contact them 10+ times in the past 2 weeks and have sent numerous emails to support with no reply. No one has ever answered the phone and I'm always sent to voicemail. It frustrating trying to operate a medical office and not have our fax account work. This is something we use frequently and this issue needs to be handled right away but it's impossible to get any help.

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.
