we keep getting calls from YPR 310-862-9039 and no one answers when we pick up. we also get the same from YPR with a 216 area code. this happens about 4 times a day.
Go to https://www.donotcall.gov/ this will remove your # from all call lists for 5 years. This works for land line and cell phones.
You can also call 888-382-1222. You need to call from each phone number you have to block each number.
I also called the # back and a recording said that my number will be removed from the call list in 2 biz days
