Product: Credit card

When I logged into my account this morning. I saw that my credit line had been reduced so immediately I went to my email to check and see if I had received any notification letter or anything about this reduction prior to today XX/XX/year> ( considering today is when this took place and and today was the only day I had any kind of notice letter or anything was the ONLY day I had received or been sent any thing from Citibank informing me of a decrease with my credit limit. Which did not give me any sort of time to make financial arrangement. this is cruel and inhumane especially considering it was not being abused. There was no notices sent to me that would even remotely indicate that this would happen. A couple months ago or a month or so ago Ive initiated a dispute for {$40.00} for taking my belongings to a dry cleaner in them ruining my personal bedding and returning it to me in far worse condition than they received it. I never usually have to file claims or disputes like this XXXX or that XXXX but unfortunately, there are many large entities such as this one and that that feel that they can take us regular hard working citizens money and well just miss a few dollars but will survive. Its wrong. When this transpired I called Citi Bank and asked the representative had asked if there was a mailbox or inbox in the online in my Citibank account that I can monitor to know what the outcome of the dispute with them and the dry cleaner was the representative told me twice on the phone there was not but they would email me and be in contact with me. Yes, they did email me, but I never received anything about the outcome of that dispute. I mentioned that story with the dispute to theyre very poor with communication. This is completely unacceptable because this is just not another number another account. This is my livelihood that was affected and I dont appreciate it. There was no XXXX notification sent to me at least 45 days or any days before the date that they actually was reduced it. What I despise the most is that they waited until I made the biggest payment that theyve seen They reduced it immediately after I make XXXX large payments comparing me to standard risk consumer models the retreived my money and gave me far less available credit than what I have even paid. Its wrong. Especially for a person thats paid the almost {$5000.00} in full to them in the past. I dont believe in being neglectful and I feel like that was a fraudulent business move considering I just paid off a quarter of what I owed on the account. What I paid brought the account to respectable balance reducing the debt from about 60 % to 40.Bringing the account back down to less than half of the account limit amount was. The initial amount owed was {$6100.00} would I pay brought it down to {$4700.00} the full limit amount was {$11000.00}. As a college student who is graduating in XXXX and starting a new job/internship this really hurt me because I had anticipated on off the rest in full at that time this is why I made a large lump sum payment to show my worthiness. instead, they did something unrespectable and reduce my credit limit to less than half that amount. another thing I believe they reduced my account because of the type of transaction I had done. And also, I believe they reduced my account because I sent a XXXX XXXX to someone who had taken care of my mother, but was in a very bad situation this its unethical and again of their business, and again, I had paid it directly back.
