E*Trade Bank Bank Account Or Service Complaint

E*Trade Bank Bank account or service department,

Checking account Using a debit or ATM card Illinois

On -/-/15 my atm card was lost/stolen in downtown -. Later that night $1000.00 was taken from my account in several large ATM withdrawals, which were not authorized by me. The next morning I was informed by card security that there might be fraud on my account and proceeded to cancel my card. I filed a claim with E*Trade in writing and after 6-8 weeks they denied my claim in a letter saying the transactions were authorized and therefore will be upheld. When I asked in writing what was their evidence for the transactions being authorized were, they replied with any documents used to investigate your claim are proprietary ; and therefore can not be provided ''. I would like to see their evidence and if possible ultimately get my $1000.00 back.
