Mobikwik — LUM300 promo code not working

Address:	Gurgaon, Haryana, 122002
Website:	www.mobikwik.com

There was a mobikwik offer running on Microsoft Lumia phones as per which there was a cash back of 3600 rs to be given for LUMIA 535 phones bought before 15th Nov 2015. See the link - http://i-1.prod-cdn.webapps.microsoft.com/blob/view/-/5930460/data/1/-/Mobikwik-offer.pdf I want to complain about mobikwik not honouring this offer starting December 2015. We had bought two Lumia 535 phones for my wife and brother (both bought after 8/8/2015) online due to this offier and they were able to redeem the coupon for only 4 months (Aug to Nov) on first registered primary number ([protected]) and 2 months (Oct & Nov) on the second ([protected]). Initially we got error message “Invalid coupon code” and now we are getting a different error message saying “Coupon Balance is Insufficient” I have raised 3 tickets and opened the last ticket I raised[protected] multiple times for non satisfactory response, for which I always get a copy pasted blanket reply given below without even understanding the issue. – “We understand you are unable to redeem LUM300 promo code. We apologize for the inconvenience. This is to inform you that this promo code is only for new users who have registered with us after 8/8/15. Moreover, signup platform should be windows app. Thank you for being a valued MobiKwik customer.” I have even spoken to their customer care number [protected] 3 times – 1st time with Abhishek Singh on 21st Dec and then with Ayush Gupta on 26th Dec and again on 28th Dec with Ayush Gupta, who promised that the issue will be escalated to back end and I would get a resolution in 48 hours. However till date there is no solution given. Being a trusted brand like Microsoft and Mobikwik, I had bought the phone believing the offer and now we are feeling cheated. Can you please help us. Details are given below. Numbers registered with Mobikwik which are not able to redeem the offer - [protected] and [protected]. Ticket number raised with mobikwik - 4028567.
