Did I make mistake?

I went in Kuala Lumpur International Airport for visa run on 23.1 and they gave me visa until 23.4 when is my ticket back to home country (before that I had 2 months tourist visa).
Now Im not sure did I have to leave country after 60 days or go immigration for extansion? (I had to do that 2y ago when I was on 6 months multiple visa.)
