Repeated contact, not able to call back says disconnected

I did not answer and they did not leave a message so I called them back and got a recorded message which told me they called me because I visited their "Loyalty Rewards Website" which I assure you I DID NOT as I do not visit sites like that. He kept talking about staying on the line and I kept saying "I want a person" "I did not visit your site" stuff like that and eventually, after about 15 to 30 seconds, he said to be added to our do not call list press 2 so I pressed 2 and then hung up and hopefully will never hear from them again.

I received a call from this number.  I also received an email saying I had signed up for Walmart's website-- which I didn't.  I double checked that they hadn't used my email address to set up an account.  But it is a little concerning that I received the email and call the same week.

Keep getting calls on my cell phone 2-3 times a day.  I never answer & no message is left.  Called back the number - got a recorded message saying it was Loyalty Rewards.  Had ordered something from Walmart last week & had to give my e-mail address.  Is there a connection.  Just filed a complaint with the do not call registry.

This number has called every few days for the past few weeks. They never leave a message.
