Having to do with trustpilot both as customer but also as site owner, I can only warn everybody of you to never use or trust this site.
Customer: Write a negative review and provide evidence. If the company pays trustpilot then it gets deleted immediatley and you cannot change anything irrespective of evidence.
Business owner: Trustpilot creates a profile for you and creates negative reviews. Once you want them removed, they pressure you to give them money or they let it be like that.
