Let me try to dispel your doubts. So,
PissedConsumer can be a useful tool for expressing dissatisfaction and providing feedback to companies. While results may vary, posting feedback on PissedConsumer can get a company's attention and encourage them to address the issue. However, a positive and immediate result is not always guaranteed. It is also advisable to contact the company directly with a complaint and give them a chance to rectify the situation. It all depends on the policy and response of the particular company to feedback. My opinion is that such a platform is needed, it exists and it works.
