Who called from 7128723171

A guy called with a promotion from Dish Network. I said we are on the No call list and asked for the company name. He hung up.

Someone has called from this number without leaving a message several times.  When I called it back a few hours later, it gave a message that the number had been disconnected.

Received a call from this number; tried to call back right away and got the message that the number had been disconnected.

Number popped up on caller ID.  When i called back, it said the number was disconnected or not in service.  Obvioulsy a telemarketing ploy.

I just received a marketing call from this number advertising some sort of medical insurance.  The call started off as a recording, and then gave options to speak to a representative or to be removed.  

I chose to speak to a representative ( Alonzo ), who assured me I would be removed from their call-list.  I explained that I was already on the Wisconsin No-Call list and that I'd like the name and address of their company.

He claimed the company name to be "Prime Liberty", and he said he was calling from California but was not at liberty to give me the address.  

I asked to speak with a supervisor, and he said he would transfer me, but he disconnected me instead.  Calling back the number which appears on the Caller ID gives a message that the number is disconnected.
