I have a package “despatch from sorting center Shanghai” since 3/21 it’s been over 30 days there like that with no update. Ik packages are taking longer due to COVID19 but how long is too long of a wait before I maybe contact the seller?

How long until I get my package I ordered it a month ago and it was supposed to be 1 to 2 days shipping and I still have not received it. Tracking it only tells me that it left the local sorting warehouse so how long will it be

Too long time in ShanghaiShi PDHZ. Why? Usually, it is not so long to process packages through this sorting center. Please, explain, why at this time it's so long. Thank you! And give, please, some approximate dates for delivering
