Hello ~ Take them back for a refund as they are possibly stolen. Take a look here…

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

You need the Apple ID and password that was used when the device was first set up. If you don’t know that, you can’t remove the Activation Lock.

The previous owner needs to go to https://www.icloud.com/find/ and erase the device, then remove it from their account. If they won't do that, the device is useless. Apple won't unlock it.

Turn off Activation Lock - Apple Support.   *
