The first thing you have to do is to contact the seller and ask him to post the tracking information if any and if it was shipped via USPS even then there would be a tracking no and you will be able to track it and you can go to the Qpost and collect it,if it was shipped without a tracking no then you can approach the Qpost official on the ground floor who is having a record of shipments arrived without either tracking no or post box no and can collect your item showing necessory ID proof,but give some time for such ordinary parcels to arrive here,hope it will help
