They deserve NO STARS.
People usually go online to vent their bad experiences with a retailer or a trader and to warn others not to do business with them. I wrote about how I bought these Blu-ray movies from the NZ DVD shop, and when one of the movies was faulty, I asked for a refund, and they ghosted me. Trustpilot set up an account for me as soon as I submitted the review, then shockingly, five minutes later, they suspended my account because they couldn't verify its authenticity.
I wrote one review, and Trustpilot suspended the account they opened as a default five minutes later. The audacity for them to use the word trust as part of their company name.
