Possible sophisticated reshipping scam

The address may exist (or it may not) but if it does, you aren't going to find this "company" there.

You have been taken, but that is not the worst of it. Every package you shipped was purchased using stolen money (most likely phished or hacked credit card info.) Most likely, the shipping accounts tied to the labels you were given are also compromised--meaning that the scammers printed labels on shipping accounts they don't own, or if they do own the accounts, they most likely paid for them via a fraudulent money source.

It is very possible that you will find yoursef in the middle of a fraud investigation, as what you have done, though unintentionally, is a crime. At a minimum you should report the crime to IC3. Whether you contact local police or not is up to you, but it is definitely important that you save all correspondence with the scammers to help protect yourself.

Please notify police both where you moved from and where you moved to. You have been handling stolen property. Show them all emails, with complete headers, to prove that you are a victim, not an accomplice.
