AITA for not paying my friend back?

Throwaway. My friend let me borrow $150 two weeks ago. She gave it to me in cash so I was going to pay her back in cash. When I got paid this past Friday, I texted her letting her know I was going to drop it off to her on my way home from work. She responded by saying to cashapp her instead and immediately followed up with her cashtag. I sent it right away. About an hour later she texted me asking if I could send it ASAP. I replied saying I did. She said she didn't get it. I started panicking thinking I sent it to the wrong person but she responded before I did and said she sent me the wrong one. For example, instead of janedoe123 she sent me janedoe13. I simply said yikes.

Here's where it gets messy. She asked me if I could send it again. I didn't have it. I'm struggling right now hence the reason I had to borrow it in the first place. Even if I did have it, I don't feel like I should have to give it her. If it was my mistake I would have figured something out, but that's not the case here. I didn't want to tell her that though. I didn't know how to respond so I just said let me call Cashapp. Well they pretty much told me tough luck. I thought hard about what to say but eventually I texted her saying "I called them and they said there's nothing they can do. I really don't have it. Idk what else to do...." She said ok.

I haven't heard from her since then. I figured she was upset. Anybody would be when they lose money. I found out this morning though that she is pissed off with me. One of our mutual friends Ash called me. Apparently Jane believes I should send her her money and figure out away to get the other $150 back. That's not going to happen. I want to call her but I wanted to ask if I am the AH first. My judgement will determine how I approach this conversation.

Edit: Thanks for all the replies. I wanted to respond to more of you but I was overwhelmed. I didn't expect this to blow up the way it did.

Anyways, I did end up requesting the money back. They haven't sent it or course. I didn't initially request it because I didn't and still don't think they would send it, but some of you convinced me it doesn't hurt to try.

I still haven't called her, but I do know I'm not going to send any more money. I did talk to Ash more about it and she thinks I should offer to work it off. I'm okay with that. I'll call her tomorrow but I probably won't update again, but again I appreciate all the responses.
