I'm a little bit skeptic about this, It seems like reviews started too early (for a new service) and also, the users who have commented in your TrustPilot page only have a review there so this makes me wonder... Is the process manual by the way? or you're using some kind of API to make things automatic?
In terms of reviews your asking? Everything automated. We use TrustPilots API's. They auto send a review request after an order has been placed and delivered. We've actually had quite a lot of orders, but 90% of people don't leave reviews, no matter how many times we ask.
