I posted a valid complaint mentioning only facts about a service provider on one of Trustpilot its European sites and the provider complained with Trustpilot saying that they never had a contractual relationship with me. However they had. I can just not provide a pdf file of that since they only sent emails about the contract and they even cancelled it by email. This provider has an excessive high rating on Trustpilot, but I found a rare left over (only recent review) with the same complained as mine so I am not inventing anything. I sent all my correspondence to Trustpilot with this provider but they refuse to use it as evidence despite that it has full email headers. They hid my bad review of this provider. S I checked what Trustpilot does to generate revenue and it turns out that they have this provider as a customer, and most likely get revenue from them. I saw for example a subscription fee they charge of $595 but other fees are on request only. So clearly Trustpilot is not an objective review site, but siding with the vendors and providers as it gets big money from them. Don't bother to trust them then to post objective reviews. They seem to simply manipulate bad reviews away.
