TITLE: [New Jersey] Charging unreasonably, after the service, says too late for cancel, requests full money
POST: Hello,

I'm doing my internship in US and we work with a sponsor company. I needed to visit my country and need a document for my re-entry to US. I thought I lost it, and mailed my sponsor immediately. They said they'll ship it ASAP and they did. 1 hour after shipment, I realized I found the form, I mailed them to cancel. Instead, they sent me an invoice and said too late to cancel now. 

Now they're charging me $100 for one page document, which was not sent with all necessary documents and arrived too late for me to use. When I say I couldn't even use the document and it was not full, they said they did what I asked for and even though I've got the service without the payment, I need to pay now. 

100$ for a document which I couldn't even use seems fairly expensive to me. Do I have any leverage here?

Thanks.
TL;DR: 
I've asked for paperwork and cancelled 1 hour after they ship it. I couldn't use it because it wasn't all documents I needed and arrived too late. Now, after the service they charge me $100.
