Mobile Store / LG Arena Km 900 Mobile — Sold phone which has problems

I went to Mobile Store,Chandni Chowk,Kolkata store on 17th Aug 2009 to buy a Business Phone, when your salesman showed me the New LG ARENA phone which had fabulous features and made me very attracted to it.
Although my Budget was Rs 15000/- but I went ahead and bought the phone for Rs 22000/-.
After using the phone I faced many problems and I suffered a lot as it’s the most Pathetic Handset I have ever used, therefore I went to the Store after 2 weeks and asked them if I can exchange it but in reply I was told that I would only get Rs.8000/- against the phone.
I feel that the Salesperson in your Store should be fully aware of the Drawbacks and Problems of a High Value Product which in this case was not true.
I was very disappointed so they told me to give it to the service center which I did but after that the problem remained same.
Now I have escalated the Issue to LG for which they have taken my phone and promised to give me a sealed pack of the same phone, which I will get some time next week.

I hope that you will be able to help me and take this Sealed Pack back and in return I am ready to take Goods worth the Current Market Price of the Phone.

Please help me with this regard and let me know in case of any concerns.

Please feel free to call me whenever necessary at +91-[protected]
