➡️ Got a call from this number with no message left; scamming telemarketer presumed. ⬅️
I think your "presumption" is unwarranted. I find no reports as a result of a brief Internet search that support anything other that the call was probably an innocent wrong number from someone (i.e., the person whose name you gave or a member of her family) using AT&T landline service.
You should be much more careful about jumping to conclusions, especially with such flimsy evidence at this point.
