Dell breach repurcussions

I was part of this databreach and began seeing strange behaviour on both my alienware laptop and desktop which were fine prior, and the laptop is actually new. They both began displaying strange system file errors, and the mouse would move on its own. I also began seeing strange emails which has cost me close to 15k in kindle books, music, movies from Amazon as somone closed my account and it was confirmed on my gmail. After receiving the letter from Dell I began frantically changing passords through 100s of vendors as I dont keep the same password for any one site. Both systems had to be reformatted and Windows 11 reinstalled costing me tons of data, although saved I had no ability to confirm with any confidense didnt also have a vulnerability. This happened shortly after updates on both systems via DELL auto updates. Amazon now states once an account is closed they cannot be reopened. I've had this account 21 years! Prior to going to an <Violations as defined by Dell removed. Read the Forum Code of Conduct. DELL-Admin> I would rather solve this amicable. The reality of what is now lost is devastating. Thank you Jim.
