Lost my Samsung S8

Hi there. I lost my cellphone, Samsung Galaxy s8, yesterday (Friday, 20/03/20). I dropped it while I was riding my bike so it was lost with a bike holder's case. On the wall paper there's a photo of my pregnant wife. Last time I tracked it, it was in post office at St Andrews Street Dublin 2, however when I went there asking for it I was told nobody had left it there. After that the phone wasn't found online again. I am afraid the battery has died. I hope someone here knows where it is. If so, you can contact me by the number 083 036 4273. Thanks in advance.
