Paytm — Credit shell refund not provided

Hi Forum,
i had booked two spicejet Airline ticket for 15th APR 2020 from surat to patna through PAYTM APPLICATION. However the ticket got cancelled as due to the 2nd LOckdown imposed. and spicejet gave me a Credit Shell to be used within an year.

As per the Governemnt of India and DGCA aviation ministry stated to REFUND the amount completely instead of Credit Shell. and Indigo airlines REFUNDED THE amount on 20th april 2020 itself to the Booking agent PAYTM in this case.

However Paytm did not inform the customer on this and they did not even credit the Refund amount to the customer. only when i was not able to use the credit shell for the subsequent use, and contacted the spicejet customer care, i came to know about this .that the refund they had processed.

now when i am trying to use credit shell in paytm, it is saying that credit shell had a validity of 1 year, now when they never notified me of credit shell then how am i responsible for its expiry.

here i am filing a complaint against paytm, please help
