I called back to find out who this is and a woman answered and claimed she knew nothing about the call and asked the time. I did not know. I looked later and it was only about a half hour after the call. I find that spammers call the first few days of the month and the last few days. I also think they change their numbers. I made an Excell spam file and put the date, time, name, what phone they called on and which ones I blocked
