I'm very new to the bitcoin (and quite frankly forum) world. I needed bitcoins pretty fast, so I used my card to buy an amount. I went through the bitcoin.com website. The company they use emailed me asking to confirm that I'd received the amount, however it hasn't shown up in my wallet. Is this normal? I need a quick reply if at all possible, the seller isn't wanting to keep his item long and will only accept bitcoin. Thanks!
