Navy FCU Bank Account Or Service Complaint

Navy FCU Bank account or service department,

Checking account Problems caused by my funds being low Georgia

My bank, Navy Federal Credit Union, has charged me for " - NSF/Return Check Fees, '' totaling $110.00. I called and disputed these fees, as they were debit card transactions, and not bank, or check drafts. Also, I was denied the right to opt-in, by the bank, several years ago, and have not opted-in, for overdraft protection. My bank has also, manipulated my posting transaction ( Debits ), so as to cause these overdrafts. With the first overdraft, I initially had sufficient funds to cover the first debit, which cause the initial overdraft.
