Xiaomi — Not refunding money

Address:

Gautam Buddh Nagar, Uttar Pradesh

I have purchased xiaomi Note 4G IMEI NO . [protected] phone 1 months ago from ebay .I started the phone but it was not connecting to wifi and mobile data so, i complained about it to the ebay customer care but he refused to refund money and told me to submit my phone at mi authorized service center . I submitted my phone in mi service center They accepted my phone & after evaluating my phone they have told me that mother board of the phone needs to be replaced which would take around 2 weeks. I have submitted my phone on on 8 aug 2015 and it's been almost a month but still they are saying to wait for the next 10 days.. kindly look for this matter
