Waka Network Too Good To Be True , Internet

Okay, so this Silvia lady calls me from a local number and says something about an online survey that I "took". At first I thought it was my job because earlier I had been sent a survey via email, from my job asking to take a survey. I only opened the survey, I hadn't even taken it yet. 

So anyways, she directs me to a site named "Waka Network" and explained I could get $100 in free gas and a Walmart card. I put in my name, address, email, and unfortunately, my credit card number and that was it. After that I started researching this "site" and all I got was scam, scam, scam and I quickly hung up.

Couldn't believe it. I immediately called my bank to cancel my card and checked my account to see if any funds were missing and everything was okay. First and last time I get scammed.
