my iphone is lost and giveng me even the last location ??

Apple does not know the location of your device.

This explains how you can find it.

If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Keep in mind that the phone will not show up on the Find My map if the battery has run down or the phone does not have an Internet connection where it might currently be located.

Unfortunately, not much that you can do about that other than keep trying every few hours to see if the status of the phone might have changed.
