Aita for giving someone my aunts number? (Work related?)

So my aunt does pet sitting for money. About a week ago, I was with her and she was complaining that she needed more money and wasn't getting enough pet-sitting jobs to pay her bills.

Today I was shopping at a pet store and overheard a conversation about someone needing a pet sitter for a cat. I gave them my aunt's phone number. I told my aunt what I did, and she got mad at me for it and said not to do it again. Shes now blowing up my moms phone about it saying that i need to learn boundaries and not to spread people's information.

Idk if i was in the wrong or not here. I was just trying to help. I know what its like to work for yourself and how you get people is by spreading the information about it.
