If she still works at that company and didn’t reply to two emails it’s safe to say she saw emails but wish to not be bothered. Unless she is the kind of person who doesn’t check work emails, we have someone like that at work. I doubt you want that kind of person’s recommendation.

The one you texted twice, did she reply to the text at all? If not, it’s likely she doesn’t want to give recommendation or be bothered at all or is just lazy.

Now is there any reason they might not want to give a recommendation? Could it be that they are not necessarily nasty people but just don’t want to recommend you. I am not saying they are right or justified in that but that might be the case with them? Or they just in general don’t like recommending people?

Sorry you have to deal with it. I’d not be calling them. Is there anyone else who could do it for you?
