MelissaData FSBO leads

Yesterday I started a Free Trail on MelissaData for FSBO’s. I started to fill in the requirements until I seen they wanted credit card info’ so I stopped. A while later I got a phone call presumably from them so I gave the credit card info.
I then received an email for instructions and was told I had to register for a Do Not Call registery that costs $62 an area code.
Then I looked at the email address and the mail was from WAS I TRICKED?
Thanks, Herbster
