I can not make a deposit on COS.TV.

Friends, I made a test deposit from the Bitru exchange, but there is no money already the fourth day, they promised me that it would take seven days to solve my problem, I just want to ask, did anyone have such a problem? and if so, how was it solved

P,S. I don’t panic, and I don’t complain, I’m sure my problem will be solved. But I just want to discuss this topic

How to buy Cos and increase Cos in Cos.tv pls
