MakeMyTrip India — flight cancelled by airline - no refund promise

Hi,
I had booked two flights from makemytrip on 11th march, 2020. The flights were the following - 1) indigo airlines 6e-5379, ccu-bom (Pnr no plnl9q), scheduled departure on 26.3.2020 and 2) air asia i5-317, bom-ccu (Pnr no oz6ess), scheduled departure on 31.3.2020. The mmt booking id is nf[protected].
Due to the covid-19 outbreak and the nationwide lockdown announced from 25th march, 2020, i had cancelled the ccu-bom indigo airlines flight through a link provided by the airlines itself via email. I had received an email from indigo airlines confirming the cancellation and assurance of a refund of the entire ticket amount. (Pfa screenshots of the mail from indigo[a])
My flight from bom to ccu got cancelled by air asia on 25.3.2020. I have attached a screenshot of the same. [b].
However, i am not being able to complete the cancellation process and claim a refund via the mmt website. It's weird that the website is showing both the indigo airlines 6e-5379, ccu-bom and air asia i5-317, bom-ccu flights in the booking completed section instead of the cancelled section. Since none of the flights ever took off owing to the pandemic, and since the air asia flight was cancelled by the airlines itself, i am eligible for a refund. However, i have been trying incessantly for the past six days to raise a claim for refund on the mmt website but have been unsuccessful so far. Every time i am clicking, raise a claim, it is showing of the cancelled flights as trips completed. Screenshots attached [c+d+e]. For the first few days i was seeing an option called 'cancelled by airlines, ' but every time i was clicking on it, the link failed and i got a technical glitch message. For the last two days i am not seeing the option only.
I have also tried the chat with ava option on the air asia website to claim a refund, but i am experiencing similar link failure issues because of the huge online traffic right now. The helpline numbers are aalso not available right now.
I am really at wit's end. I was going to mumbai for a job interview, which has been postponed indefinitely. If it does happen again also, i do not have the money to buy tickets and attend it if i do not get a refund. I am in absolute need of the money.
Here's hoping that you will understand the urgency of the situation and will kindly help me out accordingly.
Sincerely,
Sreecheta das
