have received several calls from this number, the caller will not leave a message and when I try to call the number back, a voice message prompt comes on saying that this number has been disconnected even after I have called the number back seconds after they call

Called and asked if I used a PC. I told him I used a Mac and he said "goodbye"

I got a call from this number, and a woman with a heavy Indian accent told me that my computer was receiving error messages and it was going to crash, and asked if I was aware of these messages. I use one non-work computer, and it runs great and never gets error messages. Obviously, this is some sort of scam. I promptly told her to not call me again and if they did, I would be notifying the local authorities, based on the county the area code is from. Do NOT fall for what they are trying to tell you.
