When we answer they keep hanging up. Who are these little azzes?

picked up the line on Christmas eve and heard a recording asking me to "hold for a very important call"
stayed on the line 3 minutes before it sounded like the number disconnected
I wondered if they were switching my telephone service provider

Calls from 702-553-0566 never ring long enough to be answered, rather enough to inerrupt.  No message is left; so, the telemarketer is not announcing its intention.  Our telephone-service provider says there's no way to stop the caller's automated dialing.

Received a call also they would call and only a recording asking that I remain on the line for an important message, Yeah right I just hung up. If they need a machine to tell me to wait then it must not be important

Not sure who is calling from 702-553-0566.  The recording just keeps saying "Hold on for this important call"  No live voice ever comes onto the call.

Caller ID identifies this caller from Allied Interstate@702-553-0566.
They have a number of times and tried to tell us that we owe money - different name identified but they continue to call.
I called back and they would not give me their address. All they did was repeat that we owe money even though the named person was the wrong person!

Very annoying and agrating

Allied Interstate trying to call a Ruth Smith, annoying, told them several times to stop calling.  Nothing works

called my cell and hung up.  random and annoying.

calls, no message.
