Mobikwik — Microsoft lumia 300 cashback offer

I purchased Lumia 540 and applied a code in mobikwik Lum300 . The offer was that each month add 300 and 300 you get cashback . First 3 month there was no problem but from January month problem started . And in this month March they are saying that offer is no longer valid and we can't provide any cashback on this offer though it was valid for 12 months. Firstly if you cant afford to provide such offers then don't provide them but if you are providing them then don't ruin them. Customer satisfaction is mandatory for any company to survive in market .
