Wells Fargo & Company Bank Account Or Service Complaint

Wells Fargo & Company Bank account or service department,

Checking account Using a debit or ATM card California

UNFAIR PRACTICES and CHEATING BY WELLS FARGO I have saving & checking accounts and debit & credit cards with Wells Fargo. I used by my debit card to make an online payment. I had more than sufficient balance in My saving and checking accounts to pay for the transaction in full, however to settle the transaction the bank only used money in my Checking accounts and for the rest unfairly used over draft facility tied to my credit card. So while I have cash balance in my saving accounts I have been charged overdraft fees and interest for an overdraft on my credit card. THIS IS CHEATING as logically and as a fair business practice the bank should first be using money in saving account and not my credit card. I request your help to resolve the issue
