[POSEIDON Z Owner's Club]

Hi, i have a problem with my poseidon z (blue switch). Some keys have a trouble with double clicking and some hard to click. I tried to contact the store where i bought and brought my keyboard there but they said the poseidon z doesn't have 5 year warranty, the one that have the 5 year warranty is zx version. Now i'm a bit loss because i bought it 3 years ago which means i still have atleast 1 year remaining. please help me with this issue. btw i'm from Indonesia
