Hinge defective. Miyoo claims fix is coming?

Within an hour of use the device will not close flush, and worse than others similar issues I've seen so far. I attempted a return/refund request with AliExpress, and contacted Miyoo. They are urging me to wait till February for a part replacement for the hinge. Do you all think this is a legit possible fix, or should I return and try again in a few months?
