united ending corporation?

I had a missed call from a number on my phone, and they did not leave a msg, then the other day, it happened again, i answered and they said asked for me, i said who\'s calling, and they said my name is patrick and i\'m with united lending corp. i said what is this about, and then the call was disconnected or something, so i waited to c if they called me back right away and they did not, so when i tried dialing their number back, it just goes to a vcml box, does not say what it is about, or who the company is. Now yesterday i had 3mor 4 missed calls from them, no msgs. does anyone know who this is? they are apparently called united lending corporation, i tried looking them up online and i could not find any information. thanks,
