Most smart-phones have an option to add a number to the "auto-reject list". Samsung Galaxy phones have this option. Go to recent calls and touch and hold the number. The options screen comes up and you can add it to the list.
You may check with your providor for other options
Called while i was asleep. Don't know what I said to the person. Tried to call back but this not a number. Hope I don' t hear from them or we have a fighg on our hands.
Have received numerous calls from this number and several other non-existant area codes; 273,350,875,942. If they are a real number, they are scattered all over the world and will not accept returned calls. If I answer, they ask for me by name, then hang up. They have also called and not said a word, then rudely hang up. Even in the wee hours of the morning this happens. So tired of these calls.
