Clarification on Niyo Lounge access

I want to raise a important issue regarding issue of loung pass at the end of the quarter of spending Rs 50000/- .

The lounge pass issued gets expired after 30 days of its generation.

My issue is that why it should expire after one month of generation. After all, one is spending Rs 50000/- internationally to get it . let it be there in the system or get accumulated till the time one utilizes it / them at international airport lounges at the time of his visit. This will help a foreign Indian tourist to enjoy the trip. Let there be no cut off date of its expiry after lounge pass generation.
