I got a call but didn't answer.  Generally, if I don't recognize the area code, I assume it is a scammer.  Similar numbers from this area code have been reported as 'fix computer scammers' so I'm glad I didn't answer.

someone keeps calling but when I answer they do not talk. They call every day last 7 days

Keeps harassing me by asking for a Mr. Madrid..When said there is no Mr. Madrid in this house, then ask whether I need long distance calls (it looks like an excuse)..

Some Collection Agency.. keep wasting everyone's time.

I have my number for over 7 years, and at least I get 3 -4 calls from these people a week asking for a Mr. Madrid whom I do not know.

I have asked numerous times to remove my number from their database, but they  do not do so.

this number always calling but not leaving any message

Anyone else getting calls from this phone number?
