Business ProfileforAmalgamated Bank of Chicago

I paid Amalgamated bank of Chicago $10,000 USD to open a secured credit card. if this is not clear yet, the bank provides you a credit limit based on a deposit, in this case $10,000 credit limit that functions as a credit card but using your own money. This serves to build your credit and credit line.On May 2022, I received a letter saying that the Amalgamated bank of Chicago had SOLD my secured account to another bank and two things will happen, 1-The balance will be held with the new bank 2- the difference between the credit balance and my initial deposit amount will be returned to me via check in the mail. However, the new bank claims to have bought the debt part and not the securitization amount and Amalgamated say that they don't know about the $10,000 check I gave them 10 years ago.I tried to call both banks and they keep going in circles, yet no check has delivered to me.Desired Resolution:Billing adjustment - I need the $10,000 check in the even the new bank will provide only debt OR a check for he balance between credit and securitize amount. ($10,000).Credit Correction. Amalgamated bank has ruined my credit by illegally closing my securitized credit card, claiming that I was in bankruptcy but my account was always in good standing and a SECURED card is not part of a bankruptcy, since it does not accumulate debt. Plus I have a bankruptcy dismissal.Failure to do so, will bring law suite against Amalgamated bank of Chicago.
