I received an email stating my Walmart MoneyCard had been blocked due to suspicious activity and I needed to verify my identity. I tried numerous times to upload my ID but their system would not let me. I have tried calling but just get an automated response that the card is locked and representatives have no other information, then it hangs up on me. Then today I tried logging into the app and cannot because it says that my account has been closed. The website gives me very little information and I can't use any of the services to check my account details. The listed transactions show that on *** my balance was $***.**. On ***, a DEPOSIT REFUND-Transfer from Savings of $*** was added leaving my balance at $***.**. Finally on *** it shows FED ADJUSTMENT DEBIT-Funding Reversal of $***.**. So it states I have available balance of $***. I don't know what to do and I just want my money. Please help!!
