Phone number on my cell phone call list but do not know what this is for.  Block?

Caller claim  to be  from Walmart  offering  a free  gift card  for $25.00. I NNEEDED TO PAY $ 6.95 with a credit  or debit card for  shipping. I said no thanks and hung up.

June 15 205, I received a call and the caller ID said it was from Walmart. I did not answer and let it go to voicemail but my son saw that it was Walmart and intercepted call only to immediately hang up as he knew he was not suppose to answer the phone of unknown callers, only family!  So, much later I got the number from my phone and called it.  A machine said do you want to receive a FREE gift, choose 1 for yes and 2 for no.  Since I do deal with Walmart a lot I said yes but then the phone when silent and nothing else was done or said! Strange!!! So, I gave up and decided to google the number and I found this site.  Now, I know it was some sort of scam based on the various comments here.
