My friend recommended me this exchange to trade but I wanted to KYC in advance to avoid any surprises. It may be strict, but I passed it, just followed the instructions and got verified in a couple of days. No complaints of any edited photos from them, the procedure is clear and straightforward. So far so good, hope it stays that way 
You have done advance KYC so you don't face any problem, but completing KYC doesn't mean you won't face any problem in future, they can force you to re-verify anytime because the reputation of this exchange is very bad. As many complaints have come against this exchange, they have not yet resolved any of those complaints, so what service do you expect from them? Your friend made a bad choice for you, this exchange is not a good exchange to trade.You have account in this exchange and KYC verification of that account is not a problem, my advice would be if you don't want to face any kind of big problem in future don't deposit funds in this exchange. They can block your account anytime with any excuse and force you to re-kyc and even reject your documents. So be careful.
