Ibibo Group / Goibibo — booking refund for pnr mk99gt

I am writing this mail with extreme dissatisfaction with how goibibo has handled my refund for pnr mk99gt.
Refund processed by indigo : 20, 716/-refund received from goibibo : 13, 286/-amount deducted by goibibo — 7, 430/-
Let me give you the full context here.
- i booked a mum-dubai return flight (6-jan-20 onward & 11-jan-20 return)- the return flight (Dubai to mumbai) got cancelled on 11-jan on account of bad weather and we were reallocated a 12-jan flight - the 12-jan flight again got cancelled - since both flights got cancelled from indigo and we were not even given any information on when the next flight will take off and to add to it, we were not even given any accommodation for the extended stay so we had to bear 2 day's of extra cost towards hotel stay - we realized that a few emirates flights were taking off so after having left with no alternative, we had to book us on the same at the last moment, which also cost us a bomb.
Now, goibibo is additionally charging us ~7.5k towards this cancellation. I find this totally unprecedented and uncalled for. Hence, i would request if you could reconsider this and transfer the remaining refund amount asap.
Thanks in advance!!
