Got one, No one answers and if you try and call it back sometimes it doesn't even ring or it rings once or twice and then your hung up on.

any one know this is called 10 times so far tried calling back and nothing

Same here. Been calling me all week. Pretty annoying.

i got 2 calls from them today and i didn't answer either but one was at 8:30 central time. seems kind of late to call in my opinion.

Got one as well today.  N one answers and if you try to call back it rang twice, then disconnected.  Exactly the pattern observed by Rhiana;s report earlier today.  Very odd.
