Lenovo — During warrnty period SIM slotting one pin was not detected and now charging for Rs 5000 to replace it

Address:

East Singhbhum, Jharkhand

I have brought a new smart mobile S660 (worth Rs 9100) on 13th April'2015. One year warranty is there. suddenly from 31st May net connecting SIM was not connecting with net and from 7th June that SIM was not detecting. When I went to service center they told that SIM slotting one pin got crack. And now he charged for Rs 5000 to replace the same in spite of it is in warranty period. It is not fair to spent another Rs 5000 for Rs 9100 mobile. Please resolve my issue earlier.
