Address:

I went to the mobile shop (had no name on it.just few posters of network providers.but the shop is easily identifiable since its located near kannanchery p.o kallai. right handside of road when travelling towards beypore) on 18.10.2015 to cut my idea sim to microsim and buy an adapter for the same.i was asked to pay rupees 50 after he cut the sim and the adapter of NOOSY (costs Rs.20 in other shops) was said to be of 90.I asked many times.but they didn't hear me and raised voice.I was afraid so quietly paid 50.I went to another mobile shop opposite to kallai railwaystation and bought the same adapter for 20 rupees.
