Lost bag Lost Sitges, Catalonia, Spain

The seatpost bag was inside a black plastic grocery bag. The seatpost bag is very heavy for its size due to the ebikes.ca ligo batteries inside. We took the SE19 train from Hanoi (coach 1A, seats 17 to 20) and only found the bag was missing on arrival at Ga Da Nang. It may have been forgotten while waiting on the bench for grab next to St. Joseph Cathedral here https://maps.app.goo.gl/QKE6gH5uKZ3bxhdUA or in the grab car (tried calling the male driver Lu Van Thuong +84854609118 with hotel assist but his wife answered and could not get any info) or it may have been forgotten inside the "customer service calling center" office at Ga Hanoi - the ladies that work in that office allow tourists to leave their baggage inside for a small fee while waiting for the train, the office phone number is 1900 0109 but it never worked when i tried calling... Finally the bag may have been forgotten in the train under the lower soft sleeper beds - this is the most likely scenario... We asked for the bag at Ga Danang shortly after arrival but the train was already gone... I took the train back to Hanoi the same day and asked the ladies at the "customer service center" in Hanoi but they did not let me search inside their office... I asked a lady at the train ticket counter in Hanoi to contact me by email if they find the bag but did not received any news from them. Would be unbelievable if the bag can be found, thanks Rudy :-)
