Xiaomi India — Not refund my money yet

Address:

638003

My name is Mohammed Ashik & I had ordered a redmi 3s on 21 Dec 2016 . It took it own sweet time to reach & by the time it reached i rejected the order since i was about to order 3s prime & i ordered again and got 3s prime. since the day I rejected the delivery i have still not received my refund till date which is almost a 15 days as of they after tomorrow. I would seek your help in getting this issue sorted out at the earliest & I shall make sure i will not do any more business with Mi anymore because of this experience.
My Order number [protected]

I have sent enough follow ups to the Mi Service email Id, customer support & i never get any response back to it.
Also called customer service multiple time & they have no knowledge on what rights they have to resolve this issue they simply say to wait for 10 to 12 business days
