Realme — product not yet delivered

I order an realme 5 phone on oct 13 2019 and it is estimated to be delivered on oct 17. But still now, i didnt get any notifications about delivery nor i could contact realme customer service.in my orders page (Realme site), they are saying "due to unavoidable circumstances, they couldnt deliver it". Also they are asking me when i need it to be delivered. Very worst service and now i dont even know, i will get the new phone. My order id is[protected].
