Reliance Digital — Advanced money forfeited

Address:

Lake mall Kolkata

I have paid rs 500 on 19/6/19 for purchase of laptop, but due to some uncertainty i was unable to. Today on 9/7/2020, i have come hare to buy a product in same relience digital store at lake mall kolkata but they have refused to adjust my deposit. They are now saying that it's was a 1 year old gift card.
My main question, in my gift card nothing is mentioned about the validity, also relience digital store has not informed me about the validity at the time of purchase of gift card.
If i consider that the validity period of 1 year has expired than also you should give 2 month extra validity due to lockdown because you have not given full 12 month period of redemption because your store has closed for 2 month of lockdown. Even in any other act period of stay by high court is excluded from counting the number of days.
