Unfortunately that’s more common nowadays since everything is mass produced in another country. Fortunately most places of purchase will make it right, but it takes a while. Life was so much simpler growing up in the 70 and 80s!
I just looked online and the reviews for this product are pretty terrible. Hopefully you get your money back. It's priced at $20. You should upgrade to at least the Inkbird (that's what I have). Wait till they offer it on sale and you'll only be out another $30 and have 3 extra probes and the ability to monitor your protein from Japan if you wanted.
