Xiaomi India — Mi Band - Not working, since bought

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	www.mi.com/in

I have ordered Mi band from mi.com and since I bought, it was not pairing with any phone. Later I talk to CS representative, he told me to submit the same to service center. I've not heard from service center since it was submitted., I called CS, they said complaint is closed. I haven't received any info from your side and it's closed., Where is my product I bought or refund my money., It's the worst FIRST IMPRESSION, I saw ever. WORST ONE!!
