I feel like I got scammed

I ordered some terp liquefyer as well as the kit for making your own vape juice. The amount came out of my bank, I also got an email from PayPal (it would not accept my card for some reason, so I tried PayPal, which kinda worked.) With my receipt. I didn't, however receive a confirmation email from the company.

I feel it's important to mention that their website crashed whenever I tried to create an account or send them an email via their contact link. I am hoping it's a legit thing, and that I didn't lose $20 (its not much, and I can file for a refund thru PayPal, but still)

Basically, if I need to apply for a refund, I'd like to know sooner than later, and find a reputable company to get them from.
