Scammers

I got a phone call from these people yesterday saying i owed over a grand and they gave me all this jazz about an old credit card i never paid.. I called the credit card company and they sold my debt to a completely different company!! Do not pay them! Luckily i gave them a prepaid card with only 10 dollars on it but i will surely not activate it so they cant take a dime from me! So frusterating the guy ended the breif call with gm"Good luck in litigation court" so unprofessional and attitudy i so want to call him back but im leaving it alone.
