I sent my three small grandchildren, Christmas gifts also thru the mail, and like your story, they have to this date, received nothing... I went to the post office here (TN) and asked about the missing box, got the reply there was nothing they could do to check. My daughter, went to the post office in (OHIO) and they where real rude to her..
I like you cried and I am still upset over this, because of the children. I had made all the gifts myself (knitted) and I am fighting Breast Cancer and I wanted them to have the items so they would know and remember, I love and care enough, to take the time to make them Months of work out the window,
I am so sorry to here that it happen to you and your loved ones also...
