Caller said they represent insurance coverage on my vehicle a new extended warranty on the vehicle.  when I asked a question, the woman transferred me to a warranty supervisor - who was very rude.  Wouldn't give me a quote until I gave my mileage, and when I gave that he gave me the amounts by month - as if I couldn't do the math.  when I told him the price was too high, and I said I'd think about it, he was very rude and hung up.

received a call from 3214211778. no clue who this is did not answer

I have Privacy Star on my phone, and it identified this number as belonging to Income At Home. I have blocked the number. I use the free version of Privacy Star, but if I wanted to upgrade to the premium version, the app would have blocked all calls that Income At Home uses.

Call from Florida.  Did not answer, no voicemail.

I've received 3 calls today from this number.  No message.  If I don't know who's calling I don't answer and google the number.  I've got an IPhone 6 and just found out how to block.  Go into the call history and click on the little I to the right of the number then scroll down and select "Block this Contact".  Don't know if other versions of IPhone will do this or if updating the phone software will make this available on other versions of IPhone.
