Consumer Redressal

I had a zero balance salary account with axis bank. I am employed in Indian air force and my job is transferable. I came on posting last year january to delhi from darjeeling and applied for change of address and mobile no to axis bank however bank delayed to update my bank details for online banking purpose and i was not able to carrry out any online transaction. Moreover my reward points were redeemed by me however I did not receive gift voucher till date. To add on to my problems my debit card expired the bank deducted charges for new debit card but card was never delivered to my address. I have taken up several times with bank these issues but they have failed to resolve and do false promises. Pleas help me out
