Blaming the Consumers by Nokia Care

I, Ravikumar, bought a Nokia 3110 (Classic) from a Authorised Nokia dealer from Delhi. But, After six months the Nokia handset shows its actual face to me. The set has the facility to exdend its memory. So, I am using a extendable memory card. But, the set is restart and reboot it self when we use the card / any memory card. I post a complaint and summit my set to Nokia care 4 No of time. But still they are not interested / blaming / make the consumer fool. they dont check the set and says please reinstall the set. but, I did two times what they suggested. But, the problem is still going.
