5. In view of the spread of covid-19 and widespread cancellation of many flights i opted for cancellation of my journey tickets from mumbai to tirupati on 04/04/2020 as i was covered under mmt double black. I enquired at website and found that rs.7445 was refundable to me after deducting rs.3330 from rs. 10775 i. E. The net amount i have paid at the time of this booking. And accordingly did the cancellation. I did not receive the proceeds till the end of march.

It means i have charged rs.10130 (Rs.[protected] and not rs.3330 as displayed on website while cancelling the tickets. Therefore i have been overcharged for rs. 6800.
6. Further, i also observed that on mmt website my journey dated 06/04/2020 from chennai to mumbai is displayed as completed. It’s a big surprise as all flights were cancelled due to covid-19 and nationwide lockdown. As per information displayed on your website that airlines are working on this and necessary credits will be restored to my account either on airlines website or on mmt website. But till date i am not able to find any credit note on any of the website for this journey. For this journey i have incurred rs. 5314.
