That's weird. What does the rejection message tell you?
Something like my data that i have been submitted is different from my driver license or something like that, its already about 5 days ago and i already rejected about 5 times and cannot submit KYC again, i contact them but still no solution, for now.
Have you tried Flyp.me? I never use it but it is mentioned many times here and there. Depends on what kind of coins you want to sell/buy, you'll get a different minimum exchange amount. For example, if you want to exchange ETH to ESS, the minimum amount is 0.00030497 ETH, while if you want to exchange ETH to DigixDao, the minimum amount is 0.02078974 ETH.
No, but seems pretty good since the min exchange for bitcoin is about 20k satoshi for doge. I also do quick search and found
this thread and it got mixed reviews on there.
