I have ordered MI 20800 MAH Power Bank @ 399/- and it is not working at all. Then I requested return request from there site and got mail from them that it will pick up by them in 5-7 days and their shipping vendor will call me registered phone no, 9833150592. within the next 24-48 hours for scheduling of the pickup of my return. In that same mail they mention their email id [email protected] and phone no 7531829335 which never answerable. I call on this no for at least 20/30 time but it is busy. This number is from Delhi and also they did not mention any address on the site. This kind of thing or symptoms are fraud. Dont buy anything from this site.
