[SOLVED] What do I do if my order has been "To be sent" for days now?

So, I bought a Google Pixel 7a. I ordered it from Prime Gadgets, through skroutz.gr (I live in Greece). Ever since I placed that order, it's been on "To be sent" for several days. To make matters worse, yesterday, the ETA changed from (22-2-2024 to 26-2-2024) to (23-2-2024 to 26-2-2024). What should I do?

Edit: This has been solved. it just got updated with an ETA of 27-2-2024 and now mentions a specific courier. No further advice is needed. Thanks for the help.
