Microsoft — Worst customer service provider

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I want to register complaint against MICROSOFT. I had submitted my mobile NOKIA X2-DS in Microsoft service centre on 28-Sep-2015 but till now i didn't got my mobile. I also registered a complaint in MICROSOFT but they are not responding in proper way . Instead of Nokia X2-DS they are providing me Microsoft Lumia 630 but because of its low specification i don't want to have it . I called Microsoft customer care so many times...even i have mail to them regarding this but i think they are ignoring my issue . My job sheet no[protected]/150928/010 and IMEI is [protected] . it is almost 2 and half month passed so i want a quick solution. it is my worst customer service experience now i am so embarrassed because of Microsoft customer service .
