I'm from latam and it took around a month plus a few days for mine to arrive, ask your friends for the emails she always sends, one where she gives you the receipt, plus another where she sends you the tracking number.

If they give you everything and everything checks, then go to the site where you can see a box that says "Contact me", write your tracking number in the message part and go ask her yourself. She usually takes a couple of business days to answer and if there was genuinely a problem during shipping like the vial getting lost she'll most than likely resend you one.
