Spice Jet Airlines — Refund of ticket

I booked a spice jet ticket for my brother from yatra.com platform on 22nd may for 30th may kolkata to guwahati pnr sevusq. I received a message on 25th may stating that my flight's been cancelled due to restrictions imposed by state government and my entire amount will be maintained in a credit shell. I called the spice jet customer care today (It got connected after many attempts) and they booked another ticket in spice jet for me for 30th. Pnr number is ph2lmx. I again received a message today evening saying that my flight's been cancelled and my money will be maintained in a credit shell.
As your customer, i have two questions for you:

1. If the first flight of 30th was cancelled due to state government restrictions, why did you do another booking for the same date?

2. I want my money credited to the original source of payment of my first ticket. The choice lies with the consumer if they want the refund to original source or maintained in a credit shell. On top of that, it was not spice jet's portal that i booked my tickets from, it was yatra.com's portal. So, if anything it should be maintained as yatra.com's ecash and not under spice's credit shell. Anyway, i do not want any credit shell or ecash, i want the amount to be refunded to my original mode of payment.

People are trying to reach their homes amidst this pandemic and trying to do whatever possible for that. I have emailed you but there's no response to my email. I have stayed on call for hours to just hear that you can do nothing and that my money cannot be refunded even if i go to the highest in the ladder. Just for your information, i am not blessed with a lot of money, so stop milking it from me. You are exploiting people's time, energy and their money by not being ready to refund to the source. Requesting you to stop the additional mental harassment that you are causing to your customers and expecting your cooperation at the earliest.
P. S.: if you cannot find my account details in your book, i am ready to share it with you
