I ordered a Xiaomi Power bank of 20400 mAh from Ebay. When I received the order I found that the power bank is fake. When I called them and asked them the CS executive told me that ebay is a platform where a buyer and seller meets. She was very rude. Bad customer Service I ever got from a website.
The only thing they did was they initiated my refund quickly and I received full payment in my account within 7 Days.
