defect in my note 3 neo

I am Suviraj singh chauhan. address – Tf2, malibu homes 1, 4th cross, sai baba temple road, green garden layout, kundalhalli gate, bangalore – 560037

I purchased samsung note 3 neo form the 1st block, kormanagla, bangalore branch of MOBILESTORE on 26th feb 2015.

After 10 days of my purchasse some major problem arises in the mobile –

1. back camera lens got hell lot of dust inside.

2. front camera clearity is also not that good when I compared it with another note 3 neo in other store.

3. for calling, i have to call 3-4 times to make a call, then only it connects

4. i use 3G of vodafone, and it works worse than 2G even. ( I had compared it with other cheaper samsung mobiles like grand2). the speed is very slow.

5. They said they will send the bill on mail id, which also they didn’t. Even for accidental cover and extended warranty also they didn’t provide even a single paper.

Even these mobilestore guys make u sell open seal mobile as well. Though i didn’t took. I made them to get the fresh new mobile.

I want my mobile to be replaced and I want a new one with sealed close packing.
