[Resolved]  MakeMyTrip India — booking of flight ticket

I made a booking for round trip bom-ded-bom vide booking id #nf[protected] on 13.05.2019, while booking i did apply the flymon deal code and it did show me that the same got applied on my booking and so i did the payment via icici credit card. But mmt says that the same is not applied because of that they can't process my cashback of rs. 1, 200. When i chatted with mmt, per them i have not used that code for my booking whereas i have my colleague who was present during booking and we saw that the coupon applied successfully and the respective cashback will be credited within 7 days. When i insisted for the reason they said that they will go through the booking log and will let me know about it. Now whatever the log says, my point is that i did applied the code not only for this booking but also for booking id #nf[protected] made on same date with same deal code flymon and did receive the cashback offer. Apart from this, the log is from the system maintained and operated by mmt which got no hold of the customer, and sometimes systems do operate inefficiently, neither mmt nor i can guarantee the working of the systems flawlessly.
I would request mmt to relook into this issue and refund the same to my respective account.
