I lost my wallet on -/-/2016 and called Bluebird by American Express. They stated that - ( - ) charges had been made using the card for $300.00, - and -. Once the transactions posted on -/-/2016 I called back to dispute the charges. I filled out and submitted the dispute form on -/-/2016 and on -/-/2016 they informed me via email that they had concluded the investigation and I was due no money back for the $300.00 & -. At this time I contacted BlueBird as it stated at the bottom of the mail. After an hour, a Supervisor told me that they could not tell me how they determine the outcome or what information they had. I was told the information was " proprietary '' and " confidential '', I was also told that the people who make these decisions " have no phones '' and there was " no way to contact them ''. On -/-/2016 I was told that they had finished the investigation on the $500.00 and again I was owed no money. Again the email from the bank stated to call them for the documentation they used to make the decision and again I was told that I was not allowed to see the information
