Your bank won’t help?
My SIL sent money with Chase and skipped a period in the email address, and they wouldn't do a thing to either reach out to the receiving bank or to the person who received it.
In the end, I found out who the person was and I reached out to her and she very willingly returned the money once she verified that it was my SIL who sent her the money.
Another issue is that the receiver doesn't even have a method of returning the money even if they wanted to because they don't see the email address or phone number registered where it originates from.
Zelle is very flawed (deliberately?) in its logic.
