I received a scam call from 813-310-9249. I never answer or call back.  This scam maggot has also called me using these numbers.
813-884-4237
813-310-9235
813-310-9248
813-310-9249
813-327-6066
After almost 50 scam calls with different numbers, I have up graded and just blocked the entire 813 area code.  From now on I will block the area codes of unwanted calls I receive.  I can now block hundreds of area codes.
