Microsoft — Regarding mobikwik App in the Lumia devices

Address:

Sivaganga, Tamil Nadu, 630314

Dear Sir/Madam, I have purchased one Microsoft lumia 540 Mobile phone at chennai in november 2015, with Mobikwik cash back offer of Rs.3, 600 scheme for 12 months.I got the benefit from mobikwik on november 2015 only.After that at Dec 2015 i have remitted Rs.300 through my bank and i used my Promo code to get my cash back. But the app says your promo code is invalid. Till this minute i have not yet received my cash back from mobikwik.I have made complaints by phone to the microsoft customer care officials More than 20 times.Whenever i talk with them they tell me the same answer, please wait you will get the cash back within few days.Now they are giving a contact number of Mobikwik customer care and telling me to get answer for this problem from them.I have purchased the mobile phone from Microsoft company only, not from Mobikwik.So i am lodging this complaint to get a good solution for this problem. Thank You Sir/Madam P.Nagappan
