repeated calls with no voicemail

Call with no voicemail.

Someone named "Andi" wanting to do a survey on "Air pollution" but got defensive when I asked for more details on the name of the company she was representing.

Just got a call and female voice said that "her boss wanted her to ask me 6 questions about air polution.

THIS NUMBER CALLS ME AT LEAST 3 TIMES A DAY. I DON'T KNOW WHO TO TALK TO BUT THIS IS GETTING RIDICULOUS!!!!!!!!!!

I have had 4 calls today where when answered, no one responded.  Tried *69 each time, but got an error stating subscriber does not subscribe to this service.  But on the fourth call, tried it again, and got the number 917-512-7025.  I have no clue who this would be.

Called and asked if I received a piece of mail. I said I have no clue and they asked if it was OK if they resent it. I asked 8 times who they were and they were programmed to ask about their mailing. Very weird.

I thank everyone who was kind enough to leave a message here to help others to understand the nature of these annoying calls. If this is a collection agency, which priphits from peaple's troubles, then this is a disgrace and Lord is not going to bless this kind of business.
To all of you, guys, don't give up your hope and have a merry Christmas!

THIS NUMBER CALLED MY CELL TWICE. EACH TIME WHEN I PICKED UP THE PHONE NO ONE SAID ANYTHING. WHEN I TRIED TO CALL BACK, THE RECORDING STATED THERE WAS AN ERROR #50.

3rd Day of calls from this number and like everyone else no one answers when you pick up the call.

Samething, no one talks when the call is anwered.

CALLS NO ONE TALKS WHEN YOU ANSWER THE PHONE THEY JUST SIT THERE AND THEN HANG UP

Call ID 917-512-7025. Didn't answer as I am getting use to weird number's on my phone and it's a business phone number.  Don't know if they left a message, probably didn't.
