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.

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.

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.

Hello Kyle, This is not the experience we wish for you to have. Sfax is not a phone carrier but rather a service provider so we must work with the carriers to complete the porting request. All information must match up with your current carrier for them to release the fax numbers. Please contact 1-877-493-1015 and ask to speak with someone in the porting department or message the Social Team directly at [email protected] so we may assist you further. Many Thanks, Sfax Support Team
I contacted Scrypt regarding an error message that provided their phone number. i was told that they would not help me and that if they help me, it would set a precedent for them to help other customers and they don't do that! NEVER use this company if you value respect and customer service.
