Sample letter of claim to the bank


Pearl Bank, Sucursal 118, Margarita de Ocas 234

Dear Mr./Mrs .:

My name is Gerardo Menesteiros, a client of Pearl Bank for eight years, a bank where I have a personal savings account, which was opened in December 2013 at branch 118.

I wish to inform you that I have noticed an unauthorized movement in my bank account No. 12989756330, for an amount equivalent to $ 6,000.

After reporting the problem to the Pearl Bank Customer Service department, they referred me with more than five people, without giving me a specific solution or a procedure to follow.

They promised that they would contact me shortly, which has not happened yet.

I request that my case be investigated and they give me an immediate solution, reimbursing the funds made not authorized.

Also, I demand that you give me an accurate answer regarding the origin of the problem.

On several occasions, these kinds of situations are due to errors and recklessness of the user. However, other times they respond to severe security flaws in digital platforms provided by banks.

I have been working in the cybersecurity field for four decades, so I could properly tell you that the problem did not stem from carelessness on my part.

These are the details of my bank account:

  • Account holder: Gerardo Menesteiros
  • Account number: 12989756330
  • Account type: Savings bank

Thank you very much in advance and I await your prompt response,


Gerardo Menesteiros.
