I did email Emisil the other day and they replied back to me yesterday. I explained what happened and asked why that might've happened/how. When they responded, they told me that they sent an invoice to my parents with the order and it could easily be completed from there. While this did not explain how this happened, my parents did receive the invoice, but it does not say on it what the invoice is for. Now I'm trying to convince my parents that Emisil is a safe website, and that I could email them back to see if they could create a new invoice to specify what it is for. My parents weren't paying with PayPal, but the invoice is attempting to charge them through that. It sucks that this happened, but it must've just been some sort of mistake.
