Consumer Redressal

i had brought a Nokia Lumia 520 handset from e zone, chandni chowk, Kolkata in June 2013. since then the mobile phone lock screen switch/button has repeatedly malfunctioned and i had to get it corrected repeatedly from the Nokia care center. now the lock switch is not working again. with the warranty period ending in a few months i would not be able to financially afford the repairs. i think i am being harassed by the recurring damage. therefore i am filing this complaint for your kind perusal and action at the earliest. regards Riona Basu
