Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Checking account Using a debit or ATM card California

My CITIBANK Checking Account is consistently showing systematic daily posting of debit card transactions in a descending order after they are pending for 3-5 business days. Transactions are re-ordered with the largest coming out first, then gradually the smaller ones last. This practice has been making it extremely difficult to balance my account and avoid overdraft fees. This happened before with - - -. I asked - supervisors in the customer service department, and they refused to answer my question as to why this pattern has taken place every day for at least the most recent 6 months of my transaction history. I suspect this practice has taken place since the inception of my checking account with CITIBANK. The bank also withholds my deposit funds for far too long.
