Is there a way to pull metadata on the devices that were linked to my services, e.g., VPN, Password?

Is there a way to access metadata including date, time, location, devices, IMEI or BSSID? How can I access the data myself? Or, do I need to submit an Ic3, identity theft, fraud claim and/or police report in order to get a subpoena? I experienced an account takeover and SIM swap by an intimate partner that did access my devices as well as hire a very malicious and sophisticated hacker. My ExpressVPN was linked to 6 devices including my smart TV which can be used to surveil.
