These people call me sometimes 3 or 4 times a day,I was blocking these numbers but find that all they do is change some of the last four digits and call back. Reported these numbers to the FCC didn't do any good, also call two of the numbers and told them to stop calling my number it did not do any good either both time they hung up on me after I told them that I had complained to FCC but they still call, have started making a list of date, time and number they are calling from.
