Product: Credit card

Further referencing CFPB complaint XXXX which was closed and using secure messaging or calling on the phone leads to generic responses which have nothing to do with issue and is futile. You closed the complaint XXXX stating I was ineligible for promotional rate because of me not meeting your " credit criteria ''. 
- Your promotional email, ( stating you are changing my slate to freedom card, without me ever asking to change the card in the 1st place, I might add ) stated I already qualified and am to receive the promotional rate of 4.99 % and there is " nothing else I need to do to receive this promotional rate '', hence why I received this email in the first place. Now in your response to the complaint you stated I didn't meet your " credit criteria '' to receive this rate, yet I was never notified that I suddenly became ineligible for this promotional rate that you stated I already was getting. Which leads to 2 apparent fraudulent practices. 
# 1 - since it was technically a new credit card account that you changed without asking me, CFPB states " A credit card company is generally not permitted to increase your interest rate on new transactions during the first year of your credit card account ''. Which may be negated if it is a promotional rate and doesn't fit this rule. BUT # 2 CFPB also states " ... theyre required to provide 45 days of notice before an interest rate change '' -- I WAS NEVER GIVEN ANY NOTICE, MESSAGE, EMAIL OR ANY COORESPONDENCE OF INTEREST RATE CHANGE. Even if I suddenly didn't meet your credit criteria, I still am entitled to 45 day notice of any rate change. I need further explanation of how you are able to change rates without notice even though that is illegal. 

# 2 - Chase changed my credit card from Slate to XXXX, without my authorization, nor request ; and furthermore I never signed, agreed to or otherwise even received any acknowledgment or even was able to read a credit card agreement ( which would include interest rates ) and full terms and conditions before they suddenly changed my card, so I would have no idea what my interest rate was to agree to or even acknowledge, except from the email sent out stating it was 4.99 % promotionally. How can I have an agreement with chase if I was never notified or made to sign or agree to anything? 

# 3 - You responded claiming as " evidence '' of me not qualifying for you promotional rate is that I suddenly didn't meet your " credit criteria ''. 1. This " credit criteria '' that I am to maintain to keep this promotional rate is not listed or qualified or quantified anywhere in any card documents. So essentially its a completely subjective, ie. fabricated criteria, that I am supposed to maintain, yet I don't know what I am to be maintaining?! Furthermore, your email stated I was already to get this promotional rate in your email on XX/XX/2023 when my credit score was XXXX and has been maintained in the XXXX 's range till the filing of my first complaint, so exactly when did I suddenly not meeting this unwritten " credit criteria '' even though credit score was essentially the same, and what evidence, stipulation or expectation does chase have that I suddenly one day didn't meet your criteria and therefore you can disregard the promotional rate? Because I was never notified that I stopped meeting your credit criteria, nor what the criteria even was either. 

Please explain these 3 issues, since clearly the 1st complaint did point out all the issues in this problem.
