454-545-6120

Received call from this number every day in the last 3 days, no indication of which status this number belongs, no message, tried to call back, can't connect...

No message left. I will not respond to people who  don't identify themselves.

I don't know anyone in Denmark?

No message left also no name. I  will not respond to these kind of calls.

Number repeated in name display. No message on answering system. I will not respond to this kind of calls.

454 not a valid area code, scam.

454-545-6120 had called me maybe 60 times from 12/20/17-6/7/18; on 6/7/18 I started counting and blocked the number but he called 32 more times. Then I am 99% sure he started calling from 786-292-3802.  Re: your next question, all I know is they want to hack/destroy my computer; don't know a company name.  That is why I am writing here??
