I'd reviewed many companies over approximately 7 years. My reviews were a mix of good and bad. Then I submitted a review for a company I'd received poor customer service from. The company claimed I wasn't a genuine customer and so Trustpilot asked for proof. I provided proof in the form of a receipt. However Trustpilot declined that as it was over 12 months old? So the moral is if you haven't been a customer within 12 months they will delete your review. Needlessly to say I closed my account and withdrew my reviews as I can't in good conscience continue to leave reviews for a company that censors honest reviews at the request of paid clients.
