Locks me out too fast As an efax it has many features I like and expect, tracking, ability to look back etc. But Everytime I leave the page I have to sign back in. It is often very slow to load, and cumbersome to search. It's just OK

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.

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.

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.

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.
