This happened to me as well. I ordered 2 hover boards at $499.00 each.
Same thing - order processed, with mailing label created only. I ordered on Nov. 29th. Tasharina corp.
kept telling me via email only over and over that the items had been shipped and that I would be receiving them, and that I just needed to be patient. I called Walmart.com customer service who says they can not do anything and that I have to contact Tasharina. They did provide me with phone number but no one from Tasharina corp. ever calls back.
I left 3 messages. Only after I reported it as fraud to the credit card that I used for the purchase - and they began investigating - I received an email from Walmart that the Tasharina corp. had not received their supply and that the order would not be fulfilled. They did say there would now be a refund.
However, if that explanation from walmart was accurate then why was Tasharina corp promising it had been shipped and that I just needed to be patient. They were committing fraud during this holiday season and are now getting caught.
I hope you get your refund from Walmart, also. Walmart should have to be liable for correcting all of it since it was sold on their Walmart.com site!
Reason of review: Order processing issue.
