credit card issue and cheque bounce

Dear sir, I used a credit card of a private bank from sep 2005 to aug 2006. Card has validity from sep 2005 to sep 2006. For sep 2006,i didnt use the card but they charged me with some hidden charges approx rs 6000 so on argument i paid only rs 3000 and i closed the card but i didnt get closure letter for it.they asked my card so on returned it without breaking it. After 9 years,now in the month of jan 2015,they deducted rs 10000 from my salary account as i opened it because of my newly joined company. They didnt give any prior information for this by any means and this deduction is not appearing in my account statement ,showing my balance rs 10000 as earlier also . In this period ,my cheque got bounced stating insufficient fund but sufficient amount was there.this also not appeared in my account statement. Now i filed this to rbi ,as i didnt get clear response for my cheque bounce Your guidance is highly appreciated in this regard.
