[Resolved]  HDFC Bank Bank / Fixed Deposit — Interest rate for senior citizen

I am a senior citizen.The HDFC bank has been promissing to give .5 % extra interest on fixed deposits by senior citizen.I had booked two fixed deposits nos [protected] in January 2009and [protected] in march 2009. The prevailing interest rate was 9.5%and 8.5% respectively for people other than senior citizen. The bank gave me the above mentioned rates of interest and not addional .5% which they profess to pay to the senior citizen. I represented about this. the bank authorities verbally communicated to me that they will provide the additional interest .But even though months have passed the bank has not given me the addional interest.
This amounts to defficiency in service,mislesding propganda,haraaqsment and unfair practice for which the bank is liable to be prosecuted under the law.
I request immediate action in the matter.
