Query: Top gets unlocked and pops off from tube

Ordered this in September to make sure I'd have it for Christmas! Looked great online... Top and bottom each screw on and "lock" onto the tube section. It makes a few cookies and it ends up that either end will pop off - somehow it becomes "unlocked" as it ratchets down onto the dough. Big disappointment!
