Product: Credit card

On XXXX  I made a purchase on my credit card that didn't turn out as promised so I had no choice but to file a dispute on the charges. 
The dispute department for chase slate dropped the ball on numerous occasions. 
Some of the representatives were very professional with excellent reading comprehension skills others not so much so typical do the bare minimal to not get fired or reprimanded. I have never filed a dispute for the wrong reason yet some the representatives as well as 2 supervisors were very rude and condescending and after more than year I began to become very frustrated with what I saw as willful neglect of duty and disrespectful and I in turn allowed myself to get drawn into the negativity and got very disrespectful myself. ( Which I'm sorry for losing my temper and using profanity ) In losing my temper twice in this year long saga I made 2 supervisors stoop to making their professional duties and making the issue with me and my filed dispute personal and they were going to ensure that my dispute would be closed at any cost. 
The last supervisor ( I believe to be named XXXX XXXX got upset with me for asking for her employer identification number or a name it went down hill from there. I asked to speak to her supervisor to avoid escalating tensions and she said she had no supervisor and I said so you are the top in command she didn't answer I said what about XXXX and she said XXXX doesn't work for chase. 
Within 1 day she again closed my dispute disregarding supportive documents and in a retaliatory manner closed my chase slate account in good standing for many years. Maybe she is the top dog? 
Code of ethics and conduct violations Willful neglect of duty violations Abuse of authority after making a professional problem personal .The behavior ( especially hers ) erodes public trust in financial institutions as a whole not just the chase slate company that is tarnished to say the least by both mistakes made along the way and worse yet for the blatant abuse of the supervisors position she holds at chase bank from a legal position and even worse a moral and or spiritual position. 
I know the latter isn't regulated or able to be enforced however it still is a big stain on the integrity of the company she works for. 
I have always kept me credit in good standing and I take pride in my honor and integrity and unfortunately when someone attacks that pride I sometime get drawn into the negativity and return some negativity back. I regret that and I'm sorry With a XXXX balance on my chase slate card one might ask after more than 1 year being told no on this dispute why is this still an issue for me? 
Answer because I never got my money returned because I had substandard representation as well as vindictive staff from Chase slate sabotaging my dispute My account was closed without warning or any due process or even an explanation as to why. I spoke to additional Chase slate staff to find out why my account was closed and all of the 4 different staff members all of them were not permitted to give me the reason and that i would receive correspondence via XXXX mail as of the date of filing this complaint its been more than 1 week with no answers which paints a clear picture of retaliatory unethical behavior ( XXXX vs board of education )
