Have I been scammed?

UPDATE! The tracking has now updated as being in the country. I will update again, when I have it in hand. Thank you all for the assistance.

Hi all,

For complete transparency, I am a newbie. I have ordered from a TD on her (will not mention name as I don't want to cause any upset if its normal)

I was sent my shipping confirmation nearly 3 weeks ago, every time I click on the tracking it just says "waiting for seller to dispatch". I have reached out to the seller and have just been told its waiting on the flight. I know shipping times differ but I regularly have goods shipped from China to the UK and the avarage turn around time is 1.5weeks in total. Is this normal?

I also notices on the shipping confirmation email they attached a photo of a royal mail shipping label that was 48 tracked but the royal mail website doesnt recognise it.

Please let me know if I'm just being overly worried or If I have potentially been scammed.
