Blackberry — Defective device

Address:

Gurgaon, Haryana

Hi, I have purchased Blackberry Q5 phone (pin 2B21DDFE) in August 2013 through Reliance store in Gurgaon, Haryana. Since that day the slip flip cover (from where sim and memory and is inserted) is out. I face a lag while using the phone I have restored to company setting several times but still the issue is not being resolved. I have also updated the phone software but still phone gets hanged very every now and then. When I bought this phone I was getting a very good battery backup but within 3-4 months the phone's battery backup has reduces drastically. While using the internet tethering feature (to connect net from my phone). I face a severe challenge as it keeps on getting disconnected. When I use 3G internet on my device it does not work properly, however when tried using 3G network on my other device my sim worked perfectly fine Sometimes the keypad do not respond properly specially the left caps key. Noise cancellation feature is not responding properly. I have recently purchased this phone after considering the blackberry old track and the services that has been delivered by the company but I am very much disappointed when I actually used this device. Please resolve my problem. Regards, Dhairya Kaushik [protected]
