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.

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.

It's OK It's OK. They don't have business plans that will benefit businesses. They charge lots of money for overage. I pay more in overage than plan. I provided them an opportunity to partner with my EHR company so that their software can be invoked from within EHR. They didn't care.

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?

I have been a customer since April… I have been a customer since April 2017. Any time there is a customer service issue, it's concerning. For example, I have emailed and called 3 times this week. I just emailed again today. I need my fax to work. My billing is up to date, yet there are errors preventing me from changing my password. Customer service has been awful.
