I do not answer calls from callers I do not recognize, so I let this go to the answering machine.
They did not leave a message so I am blocking this number.
I am on the do not call list but that only works for legitimate businesses, so this is most likely a SCAM.

Called ID says Walmart stores. Left no message.  I don't shop there or have a card.

I received a call from this number. Did not answer and caller hung up after message.

The usual, went to voicemail, no message left

Came through as Wal Mart Stores so I answered thinking it was my Pharmacy.  I foolishly gave him all my health insurance information that he asked for in return for a pain relieving cream.  I believe I was scammed and I am a fool for giving out all our information.
