TAX1099 and e-filing taxes

I am trying to e-file 1099's using Tax1099. I must say every year there is an issue using this third party service. The error message this year is "failed to receive information". I am so frustrated. I spent 5 hours with my IT guy Monday trying to get it corrected. My IT guy suggested contacting Tax1099 support which I did. They have been less than helpful. No phone number to call! Only emails back and forth with very little information on the solution. When they email a suggestion, it is something I have already tried. It has been a full day to get a response from them. I am running Enterprise Solutions and have a paid Payroll subscription that is up to date. I do not understand why we cannot get prompt support for them on an issue that is time sensitive. I plan to call QB Payroll support today to see if they can help. I am not hopeful. I typically use my IT guy for QB related issues, because he can fix it faster and easier than QB support. But this one even has him stumped. Is anyone else having this issue? Does anyone have a phone number for Tax1099? Thank you!
