Product: Checking or savings account

Citi Bank has just stole close to {$8000.00} from my checking and savings account which happened literally the day after I told them they can automatically transfer funds from my savings account which I had around {$11000.00} to my checking account in a occurrence in which I go overdrawn which hasnt happened in years. I did this thinking this was already a part of my account. However, the first person didnt know what I was talking about. Didnt understand English transfer me to someone else and that person supposedly did that. I wake up in the morning I open up my checking account theres for {$2000.00} transfers to somewhere I have no idea and while Im sitting there, it literally changes in front of my eyes and this is the checking account by the way those for {$2000.00} charges vanish in front of my eyes and I have less money and theres more deposits along with Posted transactions that were already posted. Timing periods that had already were pending were now posted or vice a versa. Everything changed. I logged out went to the bathroom. Came back one to my savings account. My savings account did everything besides the quantities or the screen didnt change in front of my eyes XXXX I am screenshot showing {$12000.00}. Somehow I have {$11.00} in my checking account and {$5900.00} in my savings account. This is happened before two years ago but not to the {$8000.00} extent or I figure might be even more than that, I talk to the lady on the phone from the Philippines representing Citi Bank who hung up on me when I was not in raged or even raise my voice but she was frustrated because I said yes I paid XXXX XXXX {$1600.00} where is the other {$6400.00} And she had no answer. She said I was wrong and she said I could file just a complaint or dispute and magically just got disconnected from her never called me back trying to verify my identity over and over and pretended she didnt even know that I had a savings account when we already talked about it, so basically what Im trying to say is Citi Bank who fuels calls from the Philippines ? I dont know where their headquarters are, probably New York one of the biggest banks if not the biggest bank in the world next to XXXX XXXX XXXX stole {$8000.00} from my account. I am XXXX XXXX XXXX. This is disgusting and its probably one of the employees because if you dont show that theres something that was once there and it magically disappears. Theres no evidence of it ever being there. Its a very intricate scam Im being sarcastic by the way. Basically all they do is play around with the numbers the underlying employees And then change dates periods. Post times I was told many times that a check was already posted and the lady told me oh no that was in XXXX I said it was posted the same day so someone can please call me at XXXX I am going to the hospital because I am in so much Emotional distress right now. Please leave a voicemail if I dont answer the phone please I will get back to you but I am I have to go to the hospital right now. I dont have time to deal with them as they just hung up on me I believe I might be having a XXXX XXXX as we speak or as Im writing this I should say, please call me. Thank you.
