Xiaomi India — I ordered product from mi online and its been 16 days and still not any info about my order

Address:

Bangalore, Karnataka

I had placed an order of 3 products of MI on 29 July. I also paid for that product so that is my prepaid order. They had promised me that I will get my ordered product with in 7 days but it's been 16 days and still I am not able to get my product. That hv sended me that product via courier service DELHIVERY and even they updating unsatisfied tracking details from last 7 days.
I don't know if this is the way of MI to treat their customers? This is the way to broke their promises by not delivering the product with in the time that have mentioned while product ordered by customers? I am really exhausted because of continuously waiting for my product. Even Delhivery people is not even giving any satisfactory answer. They answered that... Your product will be delivered with in 24 hours and I am listening these words 4 times from past 1 week. Help me out please... Please value your customer... I[censored] are really able to deliver my product then deliver that to me with in 24 hrs otherwise please give my money back and I will promise you not to order any single product from your company MI.
Thanks
