Freekisales — mi power bank

Hi had purchase power bank from freekisales.com. It was 1 mi power bank with 32000 mah battery and 1 wireless headset order by me for 950rps. I placed order when i received the delivery the product was sony power bank which i didnt wanted. So instead of mi i received sony. I tried calling customer care phone was switched off. I started using the product, details were mention for battery was 32000 mah battery. I fully charged the battery to 100% and soon after charging i used it and in just 10 mins battery got over and phone was not even fully charged. This freekisales guys are still doing there advertisement on instagram and other social media sites and fooling customers by fake products please do something. Product order mi power bank and received sony power bank. Which doesnt even last for 10 mins. My phone battery is 5300 mah so it suppose to atleast charge my phone for 6 times according to 32000 mah. But it doesnt even charge my battery fully.
