Xiaomi India — I am complaining about my refund

Address:

new campus, Ghus&t, Hisar, Haryana, 125001

I bought a mobile phone in exchange from their site with an orde id [protected] on 18th september. On 21 september delivery boy cancelled my exchange. So refund will be given. According to xiomi policy it takes 5 to 7 day it takes to reach warehouse but it's 10th it's still not reached to their warehouse. They are making fool like it's dispatched to bhiwandi, received at bhiwandi again and again same thing happening...
