If you don't get it, you need to contact the seller to reflect the problem and get a solution as soon as possible. Only the seller could open a case to the courier to investigate where it was delivered and who signed for it. If the seller doesn't reply you, try to contact your bank or visa company to ask for a charge back. Or, open a dispute from the platform you buy it to get refund in time.
I ordered a package and you are listed as the courier. It was coming to the US from China. Tracking says it was delivered to a local courier and delivered to me yesterday but I never received it. I need to know who the local courier was as I never got a delivery to my house. Tracking number is SNX00000194688.
