Feeling angry😡😡😡😡

My brother ordered gifts off my walmart registry and apparently my pack n play got delivered according to fedex on Friday and left at my door without the delivery driver knocking on my door or anything and apparently someone stole it. I didnt even know it was being delivered. If my brother didn’t questioned me about it not long ago I would t even know...I am so upset to the point I have the worst headache ever knowing how heartless people can be knowing something is not theirs and they gonna go to someone door and steal a damn package
