I was called from 205-259- 2694 and offered a free $100 walmart gift card plus and American Express check to cover the cost of shipping of $4.95.  They wanted a debit or credit card # from me.  This happened right after i when to my Chase Rewards Account.  I said I would look them up first while she was on the line and i saw this blog and hung up on her.

I called them back and told them I had contacted Law Enforcement and the guy cursed me out and hung up. Definitely a scam.

A similar call from 2013672172. Iprox company, that I have won cash prize of 100 dollar in walmart. And that I have 40 dollars for gasoline. The guys name is Marco Gutierrez, at least this is what the name they gave. Beware!

My call came from an unknown number, when asked what company, they answered Iprox Rewards. When i told them I would report them because I was on the "do not call" list they hung up

Received call from 1-888-907-8499 that I would receive a $100.00 gift savings card to be used at Wal-Mart or Target. I had to pay $2.95 s&h. I wouldn't provide any credit card information. Hung up. Beware, scam!!

I rec'd a call from IPROX same walmart 100.00 gift card scam...said I could also use card at best buy or target. The i only thing--the no they called from was 347-429-9147. If you call it back it is a non- working number. SCAM!!!!

Received a call from a 704-251-7637 only one ring and it hangs up. Me thinking maybe something happened to the connection on my phone plus I was waiting for a reply back from interviews...so I called back...ran me through an automated system told me I won blah blah blah...quickly someone who sounds like from India picked up and told me I have won $100 rebate card for Walmart/target/best buy, $2,000 savings coupon for local retailer/restaurants, and a $25 dining certificate. Me thinking wow too good to be true...what's the gimmick? So goes and tells me but their will be a small fee to ship it out of $2.95....she probably sense I was going to hang up. She tried to convince me to check out their website or company....I was not able to pull any thing up by the company name Iprox premium company- website discount rewards.com....she kepted on saying what ever you do don't hang up..she said that 3x....from there it was a wrap...hung her up....read all the reviews online and  they went through what I went through. So be aware, you could be a possible victim and you might not even know it!

Report any such scam, even if you did not become a victim by falling for it,
to the F.T.C. (Federal Trade Commission).
Your local phone company should be able to provide their number, or see: http://www.ftc.gov/
or see:
http://www.ftc.gov/faq/consumer-protection/submit-consumer-complaint-ftc

Informing them of such problems will give them an idea of how frequently and where the problems exists, so that they may be able to better track and maybe deal with the perpetrators.

It is illegal for anyone, even Walmart, to charge you money for winning a prize (or "postage" or "taxes", etc.)

What happens is you send them the money and they never send you anything. The Caller ID is spoofed so you have no way to trace them.

I received a similar call.
1) I do not think the Walmart leadership would approve of such a negative use of their company name, as this certainly tarnishes the "brand" which they've invested so much to cultivate.

Someone (probably a robo-dialer) repeatedly called my home phone and hung up quickly after just a couple of rings. A number was left on my caller I.D.
Then, I called the number back several times. It seemed as though they were calling on behalf of Walmart because they used Walmart's name, promising a Walmart Voucher as a free gift. I expressed extreme disinterest and disapproval.

They were very uncooperative, and they did not want to let me speak to supervisors. They also tended to ignore whatever I said as they kept returning to their sales script.

They claimed to have gotten my number from someone that I purchased something from, but I do not give my number out in any way or for any transactions.

They claimed to be a company called
"Iprox Premiums" out of "Tampa, Florida."
The number that was left on my caller ID (which I called back) was 281-860-2281. This was a Houston 281 exchange and when I asked them about it, they said they were using an "internet voice-over" to make the call.  
Several of the people I spoke with had accents from the country of India.
The phone bank supervisor's name was supposedly Jasmine Davis, but another caller also used the name Jasmine Smith.
They refused to give me information about their company -no number that I could call, no person in charge.
Rude, offensive, non-responsive (except that they would put me down as a "do not call.")
Someone needs to get a handle on telephone number and other information abuses. Attorney Generals or somebody.

Said I'd won walmart Visa card but needed my credit or debit card for shipping costs I said oh no no no not doing that and they hung up on me. I called back asked the company name they said Iprox premium rewards I asked a few more questions saying I questioned their legitimacy they hung up on me again!
