I have twice requested tracking information from a seller via eBay message. No information for 4 day

I requested twice tracking details for a purchase I made. No contact from seller then 5 days later item is marked as posted but no tracking information uploaded. What should I do with an elusive seller who refuses to reply to this request.

Does the listing specifically state that the item is sent with tracking as many ( especially small) items are sent without.

What is the seller's Handling time? 

The information for both these questions can be found in the item listing under the postage tab.

Firstly as soon as the seller generates a label eBay automatically mark the item as "posted", and secondly if the seller just posts into one of AP's Red Boxes there will be no scan until the item reaches a postal hub.

There's not much you can do until the ETA has passed, then you can open a dispute through the MBG.

What is the item number ?
