JPMorgan Chase & Co. Bank Account Or Service Complaint

JPMorgan Chase & Co. Bank account or service department,

Checking account Problems caused by my funds being low California

My checking account was overdrafted on -/-/- for a small amount ( $ -- $15.00 ). On - of -/-/- I had a deposit made that more than covered the deficiency. Chase proceeded to charge an overdraft fee of $34.00 for the small ticket item, and refused to reimburse me. This is usurious, first off - $34.00 ticket for a $ -- $15.00 deficiency that extended for less than a full business day??
