SOUTHWEST CREDIT SYSTEMS Hundreds of calls harrassing for money Carrollton Texas

I get calls from 949-407-7091 about 10 times per week for the last 2 months. Half the time, they hang up the phone when I answer. The most recent half I simply let my answering machine answer. Finally after at least 30 unanswered calls over the last 3 weeks, I answered the phone and the "Indian" Punjab voice claims he is calling regarding an important "business matter", but will not give any more information unless I confirm the name he is asking for. I told the caller to tell me the details of why he is calling and who he is or not to call me anymore and he said someone else will call from another number. I called back the 949-407-7091 a few times and their answering machine states "Southwest Credit Systems" . .  "collecting a debt",  even though I never received any letters from anybody about a debt and I have never left any unpaid bills. After waiting a few minutes with 949-407-7091 for someone to answer, they hang up every time without even saying hello. This company is conducting criminal HARRASMENT and needs to be criminally charged with stalking, nuisance, harassment, intimidation and needs to STOP CALLING from 949-407-7091 or any other Southwest Credit Systems affiliate.
