My experience with this service was very positive so far.
This is your first post here, so your words about your experience at a service won't mean much to us without proof. This is not Trustpilot to instantly trust unverified information and where everyone can give themselves 5 stars.
You can leave an honest review—that’s completely fine, even if you don’t like our service. It’s your right as a customer. However, perhaps you missed our previous messages where we explained what he actually did?
Apart from the fact that it is a fake review, you did not give us much more information, neither about where the disputed feedback was left nor which part of it is fake.
Finally, what happened to his account? Is his account even unblocked?
The fact that the accuser did not come back or provide more information after leaving the accusation indicates that it was most likely planned to leave negative feedback. However, this does not justify keeping his money.
