I ordered a power bank from bookmyoffer. After a moth the power bank stopped working and did not charged. When, I went to the authorised service centre of power bank they refused to repair the power bank that the website from which I have purchased is not authorized seller.
I contacted customer support of bookmyoffer service support they did not responded to my mails and calls. Now, I have brought power bank from authorized seller and decided not to buy from other sources without enquiry.
