Just bought a home..issue

[Raj G.]

Hi, I just bought a home like two weeks back only, seller offered to change living room window it's 5 ft by 5ft. Window should have two glass panes one inner side and one outer side.

But today I noticed that it has only one glass pane(outside), there is nothing on inner side.

it's something that tough to identify, whenever I looked through window it seems ok, but when I checked by touching then only I realized that one side(inner) of glass pane is missing.

is there any thing we can do now?
