Ok, there shouldn't be any ramifications but when we are finished, perhaps you might call and update them on your standing with our conversation. I am not an employee of JustAnswer and so am only credited (and judged) based on positive ratings here and feedback elsewhere.
Yes, what I am saying exactly is that you and the mentioned companies are not directly involved. The phishing party/scammer just uses them to their advantage, as a means to an end.
They do not have to insert any software on your own computer for this. If a friend of yours had their computer infected by a virus or other piece of malware, it may have harvested your email address and name from their address book. If you've ever entered your name and email address on a less than ethical website that later sold your email address to "Advertisers" they may have gotten it that way.
Think of it as a real letter and envelope sent through the post office. It may contain the business name on the return address and can certainly include your street address even though the unknown sender has never been in your house or had anything to do with the business it pretends to originate from...
As far as the other "people" having the same first name, this is likely not an accident and it's also just as likely that they are as "fake" as everything else.
I've received similar email myself, both from sites that I do NOT have an account with and those that I do, that were also phishing expeditions. The data mining happens when you start clicking on links and/or images within the emails as all or some may not lead to where they appear to go, or may send you through an intermediate site to capture browser data before you get there, etc...
Again, I would recommend not interacting with the emails in any way and disposing of them completely. These are not emails of note or unusual UNLESS you see other signs that you are being intruded upon in some way.
