There is nothing in the Truth in Lending Act that provides any regulation over the timing of a balance transfer. Every credit card agreement that I have ever reviewed states that the cardholder cannot depend upon the transfer until it is actually completed. Thus, the contract would control the rights and duties of the parties.
To the extent that the money was actually transferred, then the transfer is complete and you cannot reverse it.
I must admit that I don't entirely understand your facts, because it's not clear to me how you are damaged here. That's generally the critical issue in any legal action, i.e., a person who suffers no injury, other than annoyance, has no cause of action.
So, how has this transaction, or the failure thereof, actually harmed you?
