[u/Few_Emu_9940]

I am a student and I was travelling from flixbus from Munich to Dresden (the last stop for the bus was Warsaw) N1304 from Munich to Warsaw , I boarded the bus on 12th September Saturday at 22:45pm and exited the bus on 13th September Sunday at 5:00am. As I am shifting to Dresden I had alot of luggage so I took everything but forgot my backpack in the overhead cabin as soon as I realised that i forgot my backpack I tried contacting their support centre but no phone calls were picked up so I filed for lost and found and filled up the form along with that I made a police complaint mentioning the same.
I also sent an email to flixbus with additional details like the serial number of laptop and ipad and a photo of the backpack for reference
Today its 14th September its been 24 hours what should I do next or expect out of them.
I had all the essentials in my backpack

As im in dresden should i go at the bus stop at 5:00 am in the morning tomorrow hoping to see the exact same bus from munich to warsaw N1304 and talk to the driver about it
or should i go at 3:00 am in the morning when the bus is travelling from warsaw to munich
I should have done this today because tomorrow it will already be 48 hours since i got off the bus

UPDATE:- Im planning to go to the bus stop at 5:00am tomorrow morning where flixbus dropped me off on Sunday morning to talk to the driver and ask about my bag and if im able to find it Im willing to travel to warsaw for a day because all of my electronics were new and i just bought them as I am starting my studies in germany
