I've been receiving a lot of calls, on my cell phone, from exchange 716-465. These numbers are not in my contact list, so they immediately go to voice mail. No message is ever left. The numbers that have called, so far, all begin with 716-465 and are 4357; 6100; 5347; 6197; 4427; 2513; 6491; and today 716-465-8382. The caller ID is New York. I have been unable to find any information about any of these numbers on the internet.
