I just received this: "After review, we’ve deemed it necessary to close your One Cash account. Please note that we can share no additional information and that our decision is final. If you have funds remaining in your One account that are due to you, we will disburse the funds within five business days."

The interesting thing is that I've had the account open since July and haven't hit it very hard, IMO. I loaded no more than $10K total during that timespan, and kept $5K of that in the savings account bucket. I did make some purchases with the card initially, but nothing since. I guess they did not like the $500 loads. Oh, well. It is what it is.
