hacked iPhone

Did the scammer you were talking to have you install anything on your phone, or log into a website? If not your phone is not at risk. If you did either then you need to restore your phone to factory settings→Restore your iPhone, iPad, or iPod to factory settings - Apple Support. And if you gave them your Apple ID and password change the password immediately, and add 2 factor authentication to your Apple ID if it doesn’t have it already:

• Change your Apple ID password - Apple Support
• Two-factor authentication for Apple ID - Apple Support

I think someone hacked my iPhone while i was on the phone with someone who i thought was an Amazon tech but wasn't. Can you please help me and make sure my phone is safe from people trying to hack into it.

There is no known hack/malware/virus for a non jailbroken device.
