I may have ended up going into tech, but getting a pre-law degree and working for attorneys for a few years repeatedly saved me from getting totally ripped off in my early 20s. So many charlatans are only able to get away with their bullshit because they expect you to not know what your rights are or how to create a paper trail.
I once had a landlord try to withhold my entire security deposit after I moved out despite leaving the place in good shape. Just by writing a letter that A) cited the state statute saying a landlord must provide an itemized list with invoices for any repairs they deduct from a tenant’s security deposit, B) bluffed by declaring my intention to file suit if they did not (and cited the same statute again, which says that tenants are entitled to recover DOUBLE what the landlord withheld if they did so in bad faith) , and C) sending it via certified mail with return receipt (so they couldn’t claim not to have received it), they sent me back a check for like 2/3 of what they tried to withhold, plus the itemized list, plus an apology. I spent $2 on postage and half an hour on the letter and got back $300.
Another time, I got into a car accident (in which I was officially found not at fault) where the other person was driving a rental car. Over a year after the fact, I received a letter from some sketchy claims adjuster demanding immediate payment for around $2000 in damages to the other car. Once I stopped panicking, I gathered the info from my old insurance claim and called the adjuster, and some very snippy lady told me the letter was sent in error and I should disregard it. I followed up with her by email restating exactly what she told me on the phone, instructing them to work with my insurance company on any future inquiries about the accident, and threatening to involve my attorney (which I did not have) if they ever directly contacted me about it again. And again, I got an apology and saved myself a crazy amount of money.
If you are getting ripped off (or sense you are about to be), you want to ask yourself two things:
1. Can I indisputably prove that I said/did this? That they said/did this? When?
2. What rights do I have under the law? (For a lot of issues, googling “can X legally do Y” + your jurisdiction is a good place to start.)
And then, if you’re in the right, bluff. Act like you’re going to sue even if you know you don’t have the time or resources to do it. They don’t know you won’t, and even if they think they’d win, they know that would cost them more in attorney’s fees than just letting this go.
