How can I make sure respondents only answer my form once?

You can use a “Phone” field and in the settings of it turn on the “Unique” option. It will make sure each phone number submitted on your form is unique.

Also, you can embed the form on a page with cookies that don’t allow the respondent to view the form more than once (this option will require someone with coding skills on your side).
