MakeMyTrip India — correct refund not processed and paid in line with airlines communication of full refund

I had booked a flight from chennai to shirdi by indigo bearing pnr no. Jipzfz and booking reference no. Nf[protected].
Due to present conditions of coronavirus indigo vide their email dated of 22nd march 2020 informed me that they had revised the schedule for the flight and gave an alternate option for cancelling the booking at no charge.
Considering the above i had cancelled the entire booking directly with indigo as per the online option.
Upon cancelling i received an email on 22nd march 2020 itself from indigo informing the acceptance of cancellation and refund of rupees 12152/- and same to be informed to the travel agent (Ie : make my trip). I informed m/s. Make my trip regarding the cancellation through their app on 23rd march 2020 and also attached screen shot of indigo's email (As per requirement of make my trip) showing the confirmation of cancellation and the refund thereof with an advise to contact the booking agent that is m/s make my trip.
However on 28th march 2020 i receieved an e mail from m/s. Make my trip of having processed a refund of rs 152/- only, where the refund of the entire amount of rs 13272/- paid was to be considered citing the present condition of covid 19 and as per indigo's communication.
Inspite of various e mails to m/s make my trip there is no action taken by them to make the balance full refund of the booking amount totalling rs 13272/- (Including make my trip booking charges).
In the meantime m/s indigo through their replies dated 3rd april 2020, 19th april 2020 and 21st april 2020 to my mails (Which were also sent to m/s make my trip but no reply recd. From them) having time and again confirmed that full refund of the booking amount has been sent to m/s make my trip.

All the necessary communications recd. From make my trip and indigo have been attached.
