This question already has an answer here:
The website is verified by the Certificate Authority Symantec according to my Firefox browser; however, when I went to the website and foolishly bought a gift card, I then got a notification from my bank that someone spent over $400. The fees were refunded and everything was resolved; however, I am confused why the website says it's verified by a CA if it's known for scamming customers. The reviews are filled with other people saying the same thing or something similar.
Why would Symantec verify that this is a secure website, when it's not? I am no expert in IT Security, I am still at entry level and would like to know or understand this better because I am kind of confused.
