Horrendous support for Checkbox Group Validation defects

For a month now, DocuSign support has been taking me around in circles. There is a major defect in the checkbox group validation, By selecting the “Exactly 1”, or “No more than 1” validation option, the end-user should be able to check only one box out of the selected Checkbox Group (and not be able to select multiple check boxes), however this is not working as designed. The end result is the user can select (and check) all the checkboxes in the group. To make it worse, the Start/Next button function individually highlights each and every checkboxes in the group during the signing process.

I have shown this issue via screen sharing three times now, and thereafter the support team fails to send the issue to development, fails to update the ticket, and then sends me an email days later asking if I am still having an issue.

This has been an endless cycle of the following:

1. The issue is shown to support via a screen sharing session.
2. Support completely agrees the function is not working and states they will have development correct the issue.
3. Days later an email is sent to me asking if I still need assistance.
4. I respond letting them know the issue was not fixed and the issue needs to be sent to development.
5. I get on a call with them and see nothing has been addressed, and am told again the issue will be sent to development, however it never actually is.
6. The cycle restarts again with an email asking me if I still need assistance on how to set up checkboxes.
   
   I never write bad reviews but this is the absolute worst support I have ever seen, and the worst managed support team I have ever encountered.
