HappyEasyGo — I book my air ticket with goa to Chennai at 31st March but I could not find the credit shell

Address:

115c vanniyar street Ambattur kuppam Chennai 58

Due to covid-19 pandemic flights have been cancelled by the airlines and the amount have been credited in the form of Credit shell by the airlines.

now, i would like to book flight using credit shell of mine, But using your website app i could not find the credit shell or i am unable to use the credit shell provided by the airlines.

i have to contact your customer support staff for assistant for booking and i feel very frustrating and irritating to do so, because its not simple and user friendly and i dont have the option change my dates as wish.
