Consumer Redressal

I was issued a credit card from standard chartered in 2013. Initially after using my card, i didn\'t received any statement/ message notification from the bank about the usage. When this thing repeated several times, I called up the bank\'s customer care & told them about this. They reverted that my id has been updated & i will start receiving statements with immediate effect. When next time i used my card, i again didn\'t received any notification from the bank. Despite calling the customer care several times & writing to them on facebook, my problem has not been resolved. I made few payments assuming my purchases, but now, since last 3 months i havn\'t paid any amount towards the card, since i am unaware about my balance payment & usage. There is still no revert from the bank , neither they have tried to establish any contact with me.
