Personal Cash Advance Trying to get 1,189.45 that I never had Wilmington Delaware

 On April 13 my mom called me at work and told me to call this 1.877.284.1152 with this reference number SF1769409. So I called and was on his for 10 minutes then I hung up and called again and then it says this mailbox can't take any more messages. So I called again and finally got someone on the line. She told me you have a court date next week for a loan I didn't pay back of 500.00. Now I owe them 1,189.45. I never had a cash advance except from my bank. So I asked when did I supposedly take this loan they said January 24, 2014. Then I asked this guy who did I get the loan from and there number he gave me Personal Cash Advance 1.866.473.0859.
