I have used this program on several occasions and it is easy to use and makes filling out forms and sending them an easy task
I apparently didn't understand the subscription options either, like other reviewers. But after seeing unexpected charges on my CC statement I contacted them and they immediately reversed the charges. Efficient, professional, no problem. I think the subscription charges/contracts could be clearer, but on the other hand I was moving pretty fast so maybe it was my error solely. Anyway, no harm no foul. The product itself worked fine. I have no comparison so all I can say is it functions and got my job done.
Excellent customer service and support
Excellent customer service and supportI recently needed to contact them for an issue I had and was helped by Shannen. I used their Live Support Chat, waited less than 1 minute and my problem was dealt with with in less than 5 minutes. Shannen was helpful, polite and made it easy. The fact that this took such little time, without hassle was fantastic. Excellent company to deal with!
