Shipping with click and connect (dotcom zambia)?

I live in the U.S. but am sending a package to a friend in Zambia. I was recommended to use click and connect so I shipped it to their Connecticut address with my friend's name, put my email on the box for payment, and I'm registered in their website with my friends address as the shipping address. I also sent them an email with all the forwarding info and stuff but didn't hear back. When do they send an invoice for shipping cost? Or like will I hear anything from them, or do I need to reach out again at some point to make sure it's all set? I'm clueless and don't want to be annoying about it but also don't want my package to sit around forgotten because I haven't paid lol.
