Who called from 4252749181

multiple calls on my cell but I have limited calling plan so do not answer & they leave no msg.

Repeated calls to my cell phone.  I have not picked up and allow the call to go to voice mail.  They never leave a message.
I have now blocked this number.

Caller ID says "unassigned". Another scam

Keep calling. No voicemail. I didn't answer because I don't answer unknown numbers. Often calls after 9pm.

It's vacation international and they were offering a vacation package claiming that I had won it at a pet expo that I went to.  Sadly it looks like the pet expo sold my info...I guess that's why it was free entry.  She said that unless your income is over 50k, you don't qualify for this "free" vacation.  Why would your income level count if it's a free vacation that I won?  LOL!  Pathetic tactic.
