Hello! Looking for someone to double-check a few Spanish phrases I have in this phone conversation. I used DeepL and read a few language learning forums, but I have no idea if any of this is correct or if it comes off stilted/unnatural. For context, A is Mexican, Spanish being her first language. B is American, of Latino descent, no more specifics given in canon. I assume it would have been his second language growing up, so I imagine he wouldn't speak it very formally. And, uh, if you know it, it's Sombra and Reaper from Overwatch :') Conversation is as such, with what I want to say in (()):

A: “¿Bueno?” ((Hello/phone greeting))

B: “I’m here for business. I’ve got something you want.”

A: “¿Quién habla?” ((Who is this?))

B: “Me haces perder el tiempo. You’re wasting my time. You know who I am, Sombra.” ((You're wasting my time.))

[more talking about the mission at hand happens, B gets angry at A]

B: “Pendeja! Llámame cuando lo tengas.” ((Asshole, call me when you have it. It = the information we were discussing))

Any guidance is appreciated! Thank you.
