Blackberry
Non-receipt of Invoice, Charger not working, duplicate CD

I purchased a blackberry 8110 from Infibeam.com... a month back..the phone was delivered but no invoice was sent. Also, the charger doesnt work properly and there are scratches on the battery slot..I have made several complaints at Infibeam.com but still even after a month, they havent responded to my problem..Also, the CD they provided isnt working... Can anybody suggest how sue them
