Forgot luggage on flix bus need advice

On the 4th march 2026 , I boarded a flix bus number UK003 from Sheffield interchange 5:30 pm to London Victoria 9:40 pm

I reached the victoria station at 21:21 (9:21pm)

I exited & went to the Victoria underground but it was just after 10 mins I realised that I had forgotten a suitcase in the bus & it had my laptop , clothes & really important documents !

I went to check again to the arrival section of the station but saw nothing. The bus had left , then I also went to see the luggage section of the Victoria coach station to see if they got any lost property! But again they didn’t have it !

Therefore, I called the customer service , filled the lost & found property form twice with the images of my suitcase & got a confirmation email that inquiry has been sent !

I went back to the coach station again at the same time when the bus usually arrives everyday (UK003)

It was the same bus but the different driver & he told me there’s nothing you can do but wait ! The lost property baggage’s go to the depot & the lost & found team only communicates with email !

Can anyone please help me , I need the bag urgently & cannot wait for 14 days !
