Levi's India — Lost offer due to card not working at store

Address:

New Delhi, Delhi, 110018

Yesterday I went to purchase Levis jeans from jail Road, new delhi store but their card machine wasn't working and currently u know there is cash crunch due to money demonetization so I couldn't use the promo offer of 750 which was sent to me on my account.
If card machine wasn't working at the store, I guess they should accept 500/1000 currency note and submit in bank as you are not dealing in black money.
Now I have lost the offer as yesterday was the last date. I would request same offer is extended for me or some other similar offer as I had to leave oa denim which I tried and liked a lot.
