Kenwood PKG-MP18 CD Receiver with a Pair of 6-1/2" Coaxial Speakers Bundle $39 at walmart + .97 shipping

WTF is wrong with walmart website, I have tried 3 different credit cards and they keep declining
"Thank you for shopping with Walmart.com. Unfortunately, due to an error processing payment information, we have had to cancel the following order."
These are good cards,

Anyone else having issues

EDIT: I think I know what is going on, could Walmart have blacklisted my name, address or cards? During Christmas purchases I inadvertently sent a bike I bought to an old address, I caught my mistake literally minutes after placing the order and called Walmart to fix the order, the rep suggested I cancel the order because due to safety/fgraud they were unable to change the delivery address which I totally understood, the rep gladly cancelled the order and I promptly reordered the bike and all was well, so I thought

A few weeks ago I noticed that I was never credited for the original bike that I canceled so I tracked both orders and I had recieved one and the old address had also recieved on, Walmart never cancelled the first order
So I called Walmart to check, this rep now informed me that once an order has been placed online that it CANNOT be cancelled and that my order was never cancelled and I had to go to my old address to hope and get the package and then send it back, I told them BS and it was not my fault, so I called my CC company and requested a charge back

I have tried 3 different CC's and my debit card and even my Paypal and they have refused all methods of payment WTF
