Address:

R/sir,
I had submitted my 'redmi 4g note' handset at your service center new tech solution vashi navi mumbai on 8.12.2015 regarding display problem and lock /unlock key problem. Till date (For more than six month) the problem has not been solved. Your call center and service center told me wait for some days. Sir i waited for last six month, now it is very difficult to wait further. Look into this matter and give your feedback at earliest. I have taken redmi 4g note as good handset but your services are not upto the mark. Every time you taken the feedback on toll free number regarding services of your call centers and service centers but i say they useless for me for last six month.
Thank you,
With regards
