Hi @bcorbitt82 and welcome to the forum.
This squealing is a well-known (and much hated) phenomenon that can have any one of several causes. Solutions vary in complexity and require disassembling your harp and learning some skills, such as waxing/varnishing the reed ends (where the rivet is), aligning the reed correctly in its slot, or even replacing a warped reed. Because of the work involved and the risk of destroying your harp until you master the techniques mentioned, I suggest trying to return the harp to the seller and at least getting a discount on a replacement.
By the way, this happens not only on harps in the lower price range. It seems to be the result of mass production and the impossibility of completely testing each harp (in particular, testing the bends) before they are sent out for sale.
Regards and good luck,
