Received a call from this number this morning at 8:40 am. The Caller ID showed "Rsquared." This is the 3rd number identified by Caller ID as belonging to Rsquared. The other numbers are 732-479-757; 502-206-1007; and 407-519-3144. Apparently these numbers are being spoofed. Didn't answer any of the calls. Since I don't have Voice Mail they couldn't leave a message.
Same here from the 510-513-6755 number, but didn't even get a caller ID. But based on these comments, I blocked the number. It's called me two days in a row.
