Managing an account: Checking or savings account

Below is the letter submitted to Upgrade : The timing of them suspending my accont and really giving me no exact time frame on when my funds will be available. I am writing to formally complain about the suspension of my account following my dispute of charges that I believe were unauthorized. I was recently notified that my account had been suspended for allegedly violating your Terms and Conditions. However, the timing of this action raises serious concerns, as the suspension occurred shortly after I disputed transactions that I did not authorize. As a customer, I have the right to challenge charges that I believe are fraudulent or unauthorized. Exercising this right should not result in punitive action against my account without a clear explanation and supporting evidence. To date, I have not received sufficient details regarding the specific terms I allegedly violated or how my actions constituted a breach of your policies. I respectfully request the following : A detailed explanation of the specific Terms and Conditions that Upgrade believes I violated. Copies of any evidence used to support the decision to suspend my account. A review of my account suspension by a supervisor or independent department. Confirmation that my dispute of unauthorized charges was not used as the basis for the suspension.
