The deduction of money from bank account happens automatically at EOD with every broker. The one that appears in the contract note should be the same. They are most probably not charging you twice but you need to understand the charges well. As long as you have all the contract notes and bank statements you are safe.
BTW, justtrade is one of the worst when it comes to platform. They use the same one as eZTrade/SBI/Motilal Oswal uses.
