Xiaomi is having flash sale for selling its mobile phones.
The phone gets sold our in less than one second. For the past 3 months i have been trying to buy redmi 5a but how much speed i try i am unable to buy one phone but there are brokers/dealers who are able to get the phones via online sale and then they are sell the phone over ebay and taking 1000 to 1500 rupees extra for the same phone.
This is simply black marketing. Xiaomi must do something for this unless it is itself not involved in black marketing the phones.
