it is something like a simple survey.
user gets link in an email
user clicks on link and goes to a form with 4 questions ( "are you satisfied with our work ..")
text area, radios and checkbox
user fills form, store in DB
confirmation page ( "thank you" )
if user selected in radio buttons selection 4 or 5 ( bad ) then write an alert email to admin
should be a typo3 extension, just standard BE functionality, list mode
html/css not needed, just plain html, we will do it by ourself
if user already voted, he can not do it a second time.
if ticket id was already answered then alert page "you can not answer the questions anymore"
