Unvoluntary double clic and can't hold clics

Hello, after a year and half of normal use, the left button of my G305 logitech mouse will do a constant double clic when I'm trying to do just one clic. Also, when holding down a clic it will deselect the object.

I've tried contacting Logitech and a warranty of Amazon about this, and donde pretty much all the troubleshoting guides they've given me, and the problems still persist.

I think it may need a replacemente of the button, but I don't know how to do it or where could this be done, any help would be appreciated. Thank you in advance.
