Seller won’t send

[qball28]

I brought some build the titanic magazine part works  from uk 🇬🇧 On 8th of January , and tracking says accepted by post office on 10 th and tracking number uploaded on 12th, been in transit for 2 weeks ( I thought it was because says in transit) I wanted to know where in journey it was ( because not updating) I emailed seller and he replied about Royal Mail not sending internationally even though it say in transit, it still in uk 😞, even though he could send it by another courier 🚚. EBay’s rules is should be sent and on it’s way in 2 or 3 days, but still there. What should I do? Should he send dhl express at his expense as it says it should be here by 30th of January
