Consumer Redressal

Hi, Due to covid pandemic my flight ticket booked on feb 29th for may1st via smartbuy hdfc merchant site which went through the Yatra.com and finally choosing the GoAir flight. Once I found that all the domestic flights are not flying and its lockdown we could not travel and then I checked on website of goair for my ticket status. They were giving credit shell which could be used by feb 29th 2021 with one year valid. Now that I want to book a ticket they are not allowing me to use the credit shell. Also they have put a default date on my one of PNR which is dec13th and in another PNR there is no flights attached. I tried couple of time to reach the goair customer support and write number of mails but no response. Unable to reach the customer support. Same with Yatra and Smart buy are saying they cant help as they are merchant site and I need to talk to airlines. I feel cheated by the airline and need my refund. My ticket was partially booked by using the hdfc points. Let me know so that i can share my PNRs as well. Regards, Depak Jena
