I'd ordered redmi note 4 mb. On 27 june 2019. And paid 3399 by paytm. But even after the ten days i didn't receive the mb.
Website doesn't show the order and there login system is not working.
I want to know how can i get my money return. They don't have customer care no. Neither their email address is right. I've tried many times through gmail. But it is not done. So can you please suggest what to do to get refund..?!
