missed call om phone

Answered phone, thought it was my friend calling back. The person asked for me, but I played stupid. Said I didn't know when I'd be back and asked if they wanted to leave a message. Was told there was no message and they'd call back.

The phone calls started coming after I filled out a form that said I had won an ipad or iphone from a television manufacturer website. I stopped the process after I relized it might be a scheme. I was looking for christmas present. There were others phone calls also from 8574445509, 8623675500, 9173989579. How do I stop them from calling?

Received a call on my Magic Jack Plus line from (856) 295-9617. No idea how they got this number as it is a new temp number till my regular number is ported over. No message. No doubt it is from a spammer whom I have no interest in.

It is the Career Institute trying to get you to enroll in online classes.....if you answer it and it is a machine you can listen to the recording and hit a number to remove you from the list....
