Samsung — SAMSUNG NEW MODEL CORE PROBLEM IN HANDSET

Address:

Durg, Chhattisgarh

I have purchased new samsung core model. After 2 days its touchpad not working, when i gone to shop from were i purchased they said it can be now handled by samsung care. I have gone to care centre and they said it required software upgrade and they done. But another day same problem occurs. I asked for change of phone and they refused and said that it can be checked more and after that it will replace, My question how i believe that the model i purchased which is giving problem in 2 days will go long and that shop owner how he said that after purchase they will not give support. Pl. do the needful to change my phone set.
