They call 2-3 times a day but never leave a message.

this number calls at least 10 times a day and never has any sound if I picked up. So Annoying! Anyone know who it is?

Caller ID shows Mason, Oh

They've been calling me every morning for months. I finally called back today, got operator number 7 and had our number removed. It's a 'charity organization', but it seemed off, she was in a big hurry to get off the phone.

They impersonated law enforcement

no response from caller, when called back states that they are on a do not disturb feature.

States that he is calling from the law offices of Cyber Crime Unit and has multiple law suits against me. I will be arrested, as well as my supervisor. I called the number back and spoke to "Alex" who stated that he had just been on the phone with his attorney. He started going into his speech about my "lawsuits" and I explained to him that he was in severe violation of the Fair Debt Collection Practices Act. He said something a long the lines of, "it doesn't matter to me anymore" and hung up.

Called twice, did not leave messages either time

male caller claimed he was calling about a home security system which can be installed for free in your home. I told him I wasn't interested but he kept talking anyway. When asked how he got my number, he stated that he got it from an online partner, but refused to give me the name of the online partner. I told him that I was going to need to file a complaint about the company and asked him to give me the name again. He did not give me the name, but apologized and said that they will put me on their do-not-call list.
