Who called from 4242045306

Called 2/25/2015 @ 9:56 AM. No voicemail left.

Same... called no message, called back several rings... "Magic Jack customer is unavailable to take your call".

I answered the call.  It was an automated message about student loans and reducing payments.  It gives you to option to press 1 to hear more or press [idk what number since it broke up at that time] another number to opt off their list.  I pressed 2 and the call ended.

Called at 12:45pm today - I didn't answer and they left no message.

I've now received two calls from this number over the span of 10 days. Both times, they did not leave a voicemail. When I call the number back, an automated voice says, "Customer is unavailable to take your call. Leave a message after the beep. *BEEP*." I did not leave a message. Most recent call was today at 11:05AM PST.
