Notes:
My order is US22103110241860
I paid with Bitcoin
I start to have trust issues and i requested refund.
They ask me for many things i provided including email from me, proof of payment and etc. I provided everything in their telegram admin "Coco" everything including screenshot of the payment and etc.
I provided them with refund wallet because i don't have access to the wallet i send the btc from sadly.
From few hours, they are tricking me and delaying me with many stupid questions and things that had nothing to do with my order or payment.
So far i didn't received my money, and they are scamming me.
For chat logs or anything else, i can send private to admin or moderator because they include sensitive private information of mine.
