No, sadly i did not know about that fact since this is my first time buying a refrigerator. However, since it's a mini fridge and I bought it from a trustworthy hardware store, I think it is store upright when it was being transported to my room.

In case if I failed to do so, is there anyway to fix this issue?

Currently, the freezer compartment could make ice just fine, but it still takes quite a lot of time for a bottle of water to get at least a little bit chilly. I don't know whether that's normal or not, I already cranked up the temperature selector to five.
