During COVID, I took a major haircut in my day job, and ended up doing a lot of side work to stay solvent. All my banking was with Chase; I setup a new checking account for my side work. One day they just took about $900. No matter who I spoke to, they bounced me around and never gave me an answer why. I can only guess there was a fraud trigger or something, but to this day, I've never gotten the money back or even gotten an answer as to what happened. I'm fortunate enough in life that $900 isn't a big deal, but at the time, it was HUGE. As a result, I will never, never do business with Chase again (and it would be very convenient, given how many branches I have around me)
PayPal did this to me in 2004 or so when I tried to use a debit card to withdraw cash and it didn’t give me the cash but still debited the account. Hours on the phone, never got the $400 back.
I closed my account and have never directly used PayPal since.
It's not an oppositional approach. It mostly works because someone at the bank reads it who actually has the power to do something about it. Any other way that skips level-1 customer service would also help.
