Shopping Needs — NO RESPONSE AFTER SEVERAL EMAILS

Hi, I have ordered a power bank which cost Rs 502/- i.e Xiomi power bank 10400 mah and i ordered it at 22 feb 2015. But i still didn't receive this. I just got their message that your order has booked and my order id is 8855. I didn't get any email of 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. But after that their no. is not working now. 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. There service is very bull . I think they are only making money. So i request you Sir, resolve this problem soon... i saw many complaints here. I think I'm not the alone here... So i request you to take an appropiriate action against them Or tell us what we can do Further. I[censored] can check.. there is no is not working since 2 week and they are not replying the emails also. So pls do something.
