Complaints about Phone Numbers877-271-####

I have received 23 calls from this number in the last nine days. Since I do not answer calls that I do not recognize, the call goes to voice mail for 1 second. I have the phone number blocked, but it is very annoying to continue receiving these calls since they continue to clog up my calls received list.

Yes

Said his name was Kevin and I owed $300 for my computer security that was overdue was going to charge my credit card that was on file. Told me I could call this number back if I had questions. I have received these calls before & already had this number blocked. How could he leave me a voice mail ? Something needs to be done about these scammers !

Repeated calls with no one on the line when you answer
