JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Credit line increase/decrease Missouri

Earlier this month I contacted Chase through my/their credit card card web site and initiated a request for a credit line increase on - of the - I have through them. After some back/forth correspondence through the site, I was advised I was approved for the - increase requested and would receive a formal letter latter documenting the approval. Well when I got their letter I was then informed though the - increase was effected on the - card ..., they were reducing the credit line on another by -. Essentially not providing me any increase collectively on the cards. I contacted them by telephone and spoke w/ - different people and requested they restore the - reduction they took from a card not part of my beginning correspondence w/ them. They refused ...., yet suggested I could go back to what it all had been previously. I told them that was not a satisfactory resolution. Per their behavior, do I have a basis in any of the consumer laws to file a complaint against them and seek redress?
