Life / Poland's post. Lost parcel!? [4]

Hello guys
I don't even know if i choose the right thread for my question and sorry for that, but i would like to ask about Poland post, i sent since November 1 a parcel to my friend who live in Warsaw ( i'm from Athens) and parcel didn't arrive yet, i already use the tracking number with the monitoring of Polish post site and say the same status for 29 days. These delays always happen? Maybe my parcel lost? Any kind of help will be very useful

Thank you
