Xiaomi India — taking long time to deliver the phone

Address:	403513
Website:	Mi.com

My order id is [protected] and the tracking number is[protected]. I ordered phone from mi store on 6 october 2017 and today is 16 october 2017 it's been 10 days since i placed my order, but still it has not been delivered to me. The company gave assurance to deliver it within 5 to 7 business days but i have not received it yet. When i tried to contact the courier office at panjim goa, they told me that they have many pending orders, so they can't make it. And asked me to collect it from the office.. Why do you say it will be delivered at home... If you can't be manage to deliver the product at home? I am very disappointed with the courier service... Please deliver my product as soon as possible...
