Money transfer, virtual currency, or money service: Wrong amount charged or received

Optum Bank uses XXXX XXXX for investing my XXXX. I attempted to move funds on XX/XX/XXXX6 back from the investment side to the Bank side, and the transfer did not go through, and I was unable to see the transaction afterwards. I submitted 2 additional transfers, and both of those did not go through either. About a week later, all 3 transactions went through, over withdrawing the XXXX account. When I asked for this to be corrected by sending back two transfers for {$3100.00} each, they debited the Optum side but never sent it back to XXXX, putting me in a negative balance in BOTH places. Approximately 1 month later, they have failed to correct this after many contact attempts. I simply got were working on it, however, I actually work at XXXX XXXX and it looks bad on me to have a negative balance at my employer, and I am unable to use my funds for health expenses either until this is resolved. This has been a nightmare, and they shouldve never processed transactions where funds were not available, and should be processing money requests in a timely fashion, as we had to pay for the birth of our son. They repeatedly told me inaccurate balances as reflected on Schwabs side, and their systems are obviously not capable of this basic requirement for this arrangement. They have failed to move the funds back to XXXX to satisfy the negative balance, and I need help before I get fired.
