This is from an awful company called Harris Interactive. They call 3-7 times a day, even after multiple requests to be removed from their call lists. Will report to FTC and suggest you do the same.

calls 3 or 4 times a day but won't leave a message

An automatic voice systeme has called me and say "You just won 1000 Air Miles points, press 1 to accept". When I pressed 1, the automatic voice told me "wait while we are transfering your call. After the transfert, the call as been cut.

keep getting calls from this they only ring twice and then hang up

i called them back - it rang several times then stopped. I stayed on the line because it didnt disconnect me. Eventually it started ringing again and someone answered. I asked what they wanted and said i was on the do not call list. she said it doesnt matter if i am on the do not call list because they arent telemarketers and it doesnt apply to them. WTF??? She said they would take me off their list within 24 hours and was a total witch about it with an attitude i didnt like. I blocked the phone number by way of my phonecompany anyway because i dont believe she did it. Bunch of JERKS!!!

Recording announcing a sale.

At 3:18 PM I recieved a call from these people. They left no message. I don't know who they are.

5 calls per day, no one speaks when we answer.

as soon as answered, a long loud beep came from the other end. Instead of hanging up, I waited for the tone to end. It went for 27 seconds and then the other line hung up.
