No one can track it. Go to https://icloud.com/find and log in with your Apple ID. Does the phone appear in the list of devices, even if it says “offline”? If not the phone was removed from your account.
No one can erase the ID without help from YOU. Did you perhaps fall for a common phishing scam: You get a text or email from “Apple” or “Apple Security” (or sometimes “Police”) saying your phone has been found and to click on a link to see its location. This is NEVER from Apple or from law enforcement; it is from the thief or fence to steal your Apple ID and identity. Delete any such message without responding to it. Apple never gets involved in lost or stolen devices→Avoid phishing emails, fake ‘virus‘ alerts, phony support calls, and other scams
