Scammy flages for openledger.io

I am new to cryptocurrency world and i wanted to have my coins safe so didnt like to use any centralized exchange
I found bitshares to be a good choice as it claims it doesnt hold any of the user's private keys
I decided to have a try and sent some coins to my account using openledger gateway , they gave me "open.ltc" which is said to be 100% backed by real LTC
All went good so far despite i didnt know how does bitshares know that "open.LTC" is 100% backed
Till i tried making a deposite of 0.54 LTC to my account in bitshares 6 days ago , they gave my this address to make a deposite
https://live.blockcypher.com/ltc/address/LNLgZMhFfk4FZCKPzfUDhqQFQGD7dGe486/
I sent the amount to the address as seen in the URL above , but i didn't recieve any "open.LTC"
And i found that the money was transferred out of that address
I contacted openledger.io support and they just reply " please wait it may take time"
And contacted bitshares , they reply " they are third party"
And i didnt get my money back yet
I am begining to lose hope in decentralized exchanges
Bad custmer support and no guarantee for thier claims - i dont even know whether they already store the coins i deposite or just spend it away and when i ask for them they give me from new deposites
