Engraving An Item From Tiffany & Co?

so my mom surprised me at the store by buying me the heart toggle bracelet for my 16th birthday. she got it engraved and fit to my wrist too because it was a little too long and the sales rep. said that it would take about 2 weeks because they have to send it off or something. so it’s been exactly two weeks today, because she bought it on aug 22nd. it’s been paid for and everything. so i called in today and the people weren’t helpful at all, they just told me to leave a message in the sales rep. voice inbox so i did, but being the idiot i am, i forgot to leave my number. my friend said that her’s only took about 4 days to be engraved. should i go to the store? i don’t know what to do?
