I received an unsolicited email and shortly after many calls to by Trustpilot from there sales department, then out of the blue a positive review appeared on the Trustpilot company page, and I was emailed and called many times again by what I can only say is an annoying hard sell of the super expensive system which you can get elsewhere for free. The review in my case did not match a sale and I can only assume this is an underhand sales tactic possible fraud. Eventually you then receive negative review on Trustpilot you never wanted to be listed on in the first place. Then guess what sales calls and emails again trying to get you to buy in to Trustpilot and it's now its going to cost you £2,000 to £10,000, my advice is use a free review centre or directory that providers the option to turn off the review service so you have some protection against malicious activity or competitor or in he this case protection from trust pilot. Trust pilot does not add that much value and is certainly not worth anything like that money they ask. If you have already signed up to Trustpilot inform them you wish to migrate you reviews to another review company which is free and close your account. They can not refuse by law. Speak to a solicitor if they refuse.
