Trustpilot, aggressively support the business to generate revenue. There are two types of accounts for business free and paid. They don't care for free customers but if you are a paid customer they support you even you are a fake company. I had a bad experience with a company name tiptrans they remove my review and sent me an email that their system detected that review as fake and I am not a genuine customer of tiptrans now I have provided the invoice but still no action. I had a similar issue with them before as well. So I got a clear idea now, how they are generating money by supporting their paid customers(businesses)
