I am writing to you this letter to render a complaint. For the period of August 8 to August 13, 2017. My postpaid cellphone number [protected] and prepaid cellphone number [protected] call logs where forwarded to cellphone number [protected] via text by cellphone number [protected] and upon further queries I have traced the number to be belonging to a certain Mr. Emman Valencia, an employee of sun cellular telecommunications. The owner of user name E100175LUHA access my two account numbers. See attached screen-shots. I would like to know how my protected private information was maliciously released to an unauthorized third party without my knowledge and consent. Such action is a serious breach of the law and your company's privacy policies quoted below: "we strictly enforce our privacy policy within the company and we have implemented technological, organizational and physical security measures that are designed to protect your information from unauthorized access, use, alteration and disclosure. " This, I believe, is against my right to privacy as per RA 10173, also known as Data Privacy Act of 2012, protecting individual personal information in communication system in government and private sectors. I request for you to look into this serious breach and conduct further investigation and provide appropriate disciplinary action to person concerned. Such breach of privacy does not only affect me personally but the general public in nature. I fully intend to further exhaust full administrative and legal remedies if no satisfactory actions are made in connection to the issue at hand. I am looking forward to your good office's prompt and satisfactory response on the matter. Thank you.
