i have been getting random calls for the past 2 days now from this number (115733356972) it says its an invalid number when i try to call it back. but every time i called they start yelling and swearing at me into the phone asking me how long i have been with his girl. don't know who it is and i don't think its a prank call because it doesn't sound like anyone i know. but im getting very tired of these harassing phone calls.
