Kreo Swarm Naruto Edition

I'm using "Kreo Swarm Naruto Edition" from August and its working perfectly fine for me. But now all of a sudden i think my volume knob is getting lose. it feels like its clicking sound is diminishing.

I used to feel its tightness before but now i dont feel it. Also its been only been 2 months, this should not happen.

Is this normal or its getting lose by its daily usage? and is there any way to repair it like before?

Help me Guys!
