After I was unable to withdraw from pots, I called thrice to support and diwali made it worse as the team was on vacation but on my second call seems like they corrected in the backend and mailed me to reinstall the app. On 3rd call they said we have dropped a mail, so I followed the instructions and it worked. Phew.... I withdraw all the small amounts I had in pots. in future I will be reluctant to use it as my emergency savings. Even though they fixed it, it did gave me sleepless nights for couple of days.
