Product: Credit card or prepaid card

Background : I had 4 Chase credit card accounts. I used one account for both personal and business use on a daily basis. My husband has an XXXX business and we buy a lot from XXXX and other retailers. I assist him in purchasing. I usually use my Chase XXXX XXXX card as it gives 5 % cashback on purchases from XXXX. I do not sell or do any kind of rewards misuse as was stated in my account closure letter. I just bought a lot from XXXX and at the end of the month I cashed out my rewards either as a statement credit or as a deposit to our checking account. 

Chain of events : 1. On XX/XX/XXXX all my Chase credit cards were closed 2. A few days later I received a letter and it stated that I was misusing rewards 3. I called on either XX/XX/XXXX or XXXX and asked to find out details why I was suspected of rewards misuse, to complain that all my accounts were shut, and to ask for an appeal to hear out my case. I was told there is no appeal process 4. I sent an email to Chase  CEO and other executives, explaining my case. Here is the text of my email : " To whom it may concern, On XX/XX/XXXX all my chase credit cards were closed without any contact with me. I logged into my chase.com account to discover that all my cards were closed and I started to get declined transactions. 
A few days later I received a letter in the mail saying that all 4 of my credit cards were being closed for " rewards misuse ''. 

I am angry and confused. I count on chase on a daily basis for both my personal and business needs. I am angry that I was not given any prior notice. It was embarrassing for me to be in line in the supermarket to find out that all 4 of my credit cards were not usable while I had a crying baby and a cart full of food. I am confused as I was shutdown for " rewards misuse '', but I did no such thing! I have never ever sold points or done anything else to cheat the system. 

My only guess is that you don't like that I am a big spender on your XXXX XXXX card. I use this card on a daily basis for both personal and business transactions. I saw nothing in your card terms that says I am not allowed to use this card beyond a certain amount. I find it extremely frustrating that if you don't like your customers earning a lot of rewards on your card you cancel ALL of their accounts. Why don't you just cap the rewards instead? That would be a lot more honest to your customer. You advertise a card that gives 5 % cashback but cancel all my accounts when I utilize this benefit. 

In summary, I kindly request that you reinstate my accounts as soon as possible and if you have a specific issue with your customers that you call up and discuss it in the future. 

Looking forward to your response, XXXX XXXX '' 5. I got a call from the executive office on XX/XX/XXXX and was told that they couldn't give me info as to why I was shutdown and that there is no appeal processes. I was told they are allowed to shutdown my accounts at their discretion and they don't need to give a reason as to why.

Summary : 1. ) I have been falsely accused of " rewards misuse '' when I have done no such thing.

2. ) I have had suffered the embarrassment of being in line at the supermarket with a full cart and all my cards don't work.

3. ) I have had all my credit card account shutdown and was given no appeal process and an incorrect reason for account shutdown ( award misuse ). I believe the real reason is that Chase doesn't find me a profitable customer because I pay my bills off every month and spend a lot on their card which entitles me to a lot of cashback 4. ) The impact to my credit score will be astronomical as I have a lot of history with chase and had a large amount of credit with them
