How to get my money from american express blue bird?

Certegy says they have paid a returned check that i deposited but amex says it was not?
Someone wrote me a check and i deposited it into my american express bluebird account via my iphone. The check came back as return and I never received my funds. The person that wrote me the check got a letter saying that certegy has paid there check to "american express travel." We have both been on the phone with both companies. Blue bird american express keeps saying the check was returned but certegy keeps saying that they paid american express. Now the idiots at Blue bird are in india and are not helpful. I have even offered to fax them documentation from certegy and they refuse to even give me a fax number. If I call any other american express department besides the one bluebird department they tell me that they can't help me and only that department can. The people at the bluebird department can't seem to simply just look up if certegy has paid them, they just keep trying to tell me that the check was returned and try to explain what that means. I'm not stupid, I know what that means but certegy says they have paid them and I even have documentation from certegy. How do I get my money from American express bluebird that they just have setting around in some system thats not connected to the bluebird department of american express?

WeChat 40.9 mb
Temple Run 36.6 mb
Instagram 26.1 mb
Tiny Wings 17.2 mb

When I try to add it all up, it doesn't end up as much as 10.5 gb. How come its so much? Where are the other gigabytes coming from?
I always clear my safari history and I don't bookmark or favorite things on safari either. I barely have any notes. I have no alarms. I have a few birthdays in my calendar but its not much. I have I area of weather. My mail is always empty cause I check it everyday and I also always clear my phone calls. Where's it all from? When I added it up I got about 6 gb all together but where does 4.5 other gigabytes come from?
