Two days ago I took 6.65 ETH but did not invest in my account and they stalled me by saying there was a technical problem. they blocked my account today. does no explanation. they've stalled me so far and now they've blocked my account. This site is dishonest.
Telling that there was a technical problem is not a reason for you to call them scammer but, if your account was blocked by them, that should be a problem for them. First things first, before you trade on an exchange, be sure to check its review to see if they have a bad background or good.
The answer I gave them above is an explanation. The process that they need to close my account is still allowing for others.
