First PREMIER Bank First PREMIER Bank Won't send refund check for overpayment Internet

UPDATE: I sent this letter to the FPB Account Inquiry department regarding returning my overpayment funds of ($690.39) : 

Dear First PREMIER Bank, 

I am contacting you to request that you acknowledge me in writing the reason that you are holding my overpayment funds ($690.39) beyond the 30 days you originally told me you needed to be sure that the funds cleared.

I have called four times since November 13th with questions and concerns about this beyond normative time practice of holding overpayment funds, with very little help except that theyd be mailed back by December 14th. Seeing that no account action had been taken, I called on Friday, December 14, 2012, I was told you might need up to 60 days?!

Additionally, while I was on hold, your recording stated that if I am calling regarding a refund, it could take up to 30 days receive (NOT 30-60 days, etc.).

I would like to have the exact date in writing that you plan to return my funds.

Thank you, Erinn

... Looks like First PREMIER Bank doesn't want their bad dealing practices in writing... only via phone. 

Firstly, I assume you have written communication both to and from First Premier Bank for this snafu. If you don't already have it in writing from FPB, then contact them in writing and have them send you this info regarding the delay in payment to you in writing. That way you have proof of their unjustly withholding your overpayment. Once you have the proof, send it to the Consumer Financial Protection Bureau (CFPB). That is what they are there to do - protect you from actions like this where the creditor is withholding your overpayment for an unreasonable time.
