Spice Jet Airlines — Refund expected

Dear Spice Jet team
I was supposed to fly Goa to Bombay in April 2020 but bécasse of the corona virus i had to cancel my holidays in India.
I kept in touch with Spice Jet to get the refund of my ticket and it was ok to get the refund from the end of March 2021. I gave all my bank details to the refund service and so far nothing has been donne. Chasing them they say there is a technical problem. Since my last email sent about more than 10 days, no more reply from them. thaïs is ont very serious as other Airlines such as KLM or Oman Air have proceeded with a total refund.
Here are my reference

Thank you for your help
Kind regard
