Buy crypto using the wallet

Hello!

This might sound stupid, but I still ask just to be 100% safe.

if I am going to buy crypto through using the trezore wallet, how safe is it to use my credit card on it?
is there any chance that I could get scammed?

By scam I mean that if I use my credit card, how do I know that the shop/crypto bank/exchange that I buy my cryptos from via the trezore wallet will not steal my CC details? or how do I know that I will recieve my coins after the transactions? :slight_smile:
