My Review on Celcon Octa 510

KISHORE RAVI (Sep 16, 2015) on Gadgets 360

I give maximum thumbs up stars for "Celkon Service Center", in our area, but i am really disappointed and financially broken investing on this phone. I needed the help of Celkon Service Center within a month of my phone's purchase and their cooperation seemed justified but the problem still exists and now i have to invest more time (which i do not have), just to get it fixed. No response from Customer Care either. The price i paid for this phone is not easy for me,but the design is very attractive, simple and cute, and as for the performance, you have no other choice but to get disappointed the minute you pay the price. Dare to purchase this phone and you will have no choice but to agree with me. No offense. Celkon Service Center - All Stars Celkon Octa 510 - not worth mentioning half star Customer Care - Absolutely no idea if they exist. I only gave 1 star as i do not have choice and if its up to me i wouldn't waste on saying it a star.
