Don’t believe on askmebazar.com. I had bad experience . I have seen add for Sony power bank some where, I ordered Sony power bank, but instead of sony I got MI power bank. I got order by 10 days, even thy don’t have tracking system. Even they are not asking for sign up, I order as guest user, I was unable to track my order. After received MI power bank, I called to customer care, they have given 1 complaint number, and they told concern department will call you back, but it’s been 3 days I didn’t get any call from them. And they are telling they don’t have exchange policy, only they will return money. Mistake is their’s but they are not responding.
