Mts — mts dongle activation process is due from 1 month

Address:

New Delhi, Delhi

I have purchased wifi dongle on 25th of Feb, order number:[protected]. Till now it does not activated. I have spoke approx 10 time to customer care executive, they are not doing anything only saying that please email to "[protected]@mtsindia.in" along with all your document. And email sent already more than 5 time. Every time when I call after explaining every thing from starting they replay again send email to [protected]@mtsindia.in. Although I did not get any reply of any email! So I want to refund this dongle.
