blackwidow elite, the volume wheel fails

I have had this keyboard for less than a year and recently I began to notice a failure in the volume wheel, until now the wheel does not work, because when I raise or lower the volume, it moves from top to bottom without doing anything, Now the fault that I have added to the previous one is that the sound goes to a minimum, no matter what I am doing, it is a nuisance because I bought the keyboard with the support of the brand and it comes with this fault.
