[Resolved]  UniverCell — Cheating, Poor service, Selling products with faulty information

I recently bought a portable USB charger DC-16 (stick charger) from UniverCell, Ameerpet, Hyderabad. for my LG Optimus L9, I had been told that DC-16 is capable to charge my cell at minimum 2 times, the employee there himself checked my cell and suggested me that charger. But when I bought it, I found its not even able to charge my cell more than 75%. When I went back to store very next day with my complaint, same employee there refused to change charger and blamed me that I shoundn't trusted his words.
