Bumping it up again

Thank you for writing to Zerodha!!
Due to some temporary upgradation process at our back end system is unable to fetch the 60 day challenge certificate. Our technical team are working on this, you should be able to download the upgraded challenge winner certificate soon.
Also on your previous challenge there is end date showing wrongly 2017-12-02, which needs to be corrected, and if you are in profit the brokerage refund will be processed.
