We fixed everything with the user
It's easy for you to say, but would you provide some proof of that, or ideally have the user themselves confirm that?
If the above statement by bitmixcoin.io is wrong and you still need someone to tag their account, forward the letter of guarantee to me.
Little piece of advice here, btw: You are not building a strong image for your brand with the way you talk.
I'd expect something better from a public representative for a service supposedly trusted with several thousand btc each week.
The user will connect and verify our claims, The chipmixer employee just was looking for an option to roost us.
I can promise you, after the user will verify our claims still no one will remove our negative feedbacks.
