Shopping Needs – not refund money

Hi, I have ordered a Xiomi power bank 10400 mah and i ordered it at 24 feb 2015. But i still didn’t receive this. I just got their message that your order has booked and my order id is 8508. I didn’t get any email about shipping. then i called several times that i didn’t receive the tracking no of courier. So they replied we will call you.There is option of complain ticket in their website. I several time emailed them and launch new complain tickets. But they remove after 3-4 days without resolve the problem… my contact details are snehal vayeda 09714713120…
