Texted me randomly, I don't know who they are
Category: Unknown Caller
Calls are coming into my cell phone from this number constantly.;<br />Due to physical problems, it is causing me a great deal of agony.
Category: Telemarketer
I get telemarketing phone calls from this number and others constantly. They are some sports betting company that try to tell you who to pick. I have been able to get a live person on the phone only 3 times and each time I request to be removed from their call list but they always hang up on me before I can get it all out except for the very last time. Do not answer this call and help me in figuring out how to report this company for harassment.

Category: Debt Collection
<br />Watch out for these people. They claim to work for Cash Advance America, which is a legitimate company but not through these people. They'll even tell you to go to the BBB and look them up, sure there are legitimate Cash Advance America's but THIS IS NOT ONE! They are scammers and will insist on $100 "good faith" payment prior to your loan. After that they will tell you that you have been red flagged by the Federal Trade Commission and demand another payment of $151 to remove you from the red flag. Which is another part of the scam.
