Product: Credit card or prepaid card

1. On XX/XX/XXXX We disputed the credit card through the Citi credit card with the reason the law firm doesn't provide the job and service to us. the Citi card rejected the dispute and unwilling to reopen the case with the reason the Citi credit card is not allowed the consumer to using the credit card to pay for the services. I never heard about it and then I requested the Citi card to provide me the policy regulation statement by email per reason rejected disputed. Citi credit card company unwilling to provide me what she was told me about it. I feel unfair as a consumer without the protection from the credit card company. I emailed again to upper management and none of them respond back to us.

2. We paid the law firm for the retainer fees to answer the court or plaintiffs from our company check with total amount of {$20000.00}. The law firm wants me to signed an agreement as additional contingency fees {$30000.00} to filing the malicious prosecution lawsuit against the plaintiffs. But none of the job and services performs on the case at all. The law firm keeps ignored and quite after the firm got money from us.

3. The credit card total charge rejected dispute is {$30000.00} which is as below : a ). 10 X {$2500.00} = {$25000.00}, which the law firm signed the agreement with me the firm will do deposition, discovery, and summary judgment and cross-complaint back to the plaintiffs which they already know we were innocent. But none of the jobs and services has provided to us and no movement we received the services until the case was dismissed by plaintiffs and court. 
b ). The law firm contacted us on XX/XX/XXXX said the case will go for trial around XX/XX/XXXX. He requested me to pay another {$5000.00} for the trial fees and we agreed to the law firm to charges the credit card on XX/XX/XXXX. After charges, the {$5000.00}, on XX/XX/XXXX, the lawyer emailed us said the case was dismissed by plaintiffs and the case was closed by plaintiffs. We don't have a copy of any court paper as show dismissed from the law firm, he just email said case dismissed he received XX/XX/XXXX. Since the case was dismissed by plaintiffs, none of the jobs and services the law firm has been a show to us. We asked for the action, the law firm ignored and no responding email or call. Today XX/XX/XXXX, I search the case online ( attachment is dismissed court filing ) to see when and what date the case dismissed ; the case was dismissed on XX/XX/XXXX with proof of the filing from the court. That means within 21 days, the lawyer already knew the case was dismissed but he never told us and still lied to us that he was still preparing for the trail. After the law firm charges {$5000.00} on XX/XX/XXXX, he told us on XX/XX/XXXX cases dismissed, we got scam this {$5000.00} again by this law firm. The law firm was dishonest and scam, since we paid {$30000.00} as he promised on the agreement to do based on the agreement, none of them he provides and performs to the client. We explained to Citi why the reason we disputed, as Citi must understand the reason we disputed the credit card. But the Citi was very rude and dont let the client explain. The city disputed dept said they dont need to know. Its very disappointing as the credit card provider was treat very unfair and no professional. 
I am seeking to help upper management Citi to re-open disputed the case. If you need any additional information, please let me know. Thank you
