I RECEIVED SEVERAL CALLS FROM THIS NUMBER AS WELL. WHEN I CALL BACK IT JUST SAYS ENTER YOUR LAST NAME. I HAVEN'T DONE SO BECAUSE I DO NOT KNOW WHO IT IS.

Just did a Google search on this number and here I am.  No message and won't bother calling back.

Calls received from this number 5 times between 10:20am and 10:40am. Never left any messages.  When I call number back they do not identify themselves and ask for personal info.

Got several calls from them. Decided to call Horizon to investigate, they stated that the call is not from them but from one of their suppliers. Horizon stated that the caller is just trying to get answers for a survey but you are not obligated in anyway to answer the call. Also if the Horizon representative said that the survey people CAN NOT ask for date of birth SS number or policy type or number. I haven't answer the survey call either just in case. Hope this helps.

I believe this a call back from a call I placed to Horizon regarding a 1099 that was sent to me regarding interest income.  Very confusing.
