[Resolved]  CESC Ltd, Kolkata — Non payment of interest for deposit in CARS a/c

For easy payment of monthly bill sent by CESC I opened CRES a/c with them and replenish it with fresh deposits.
In last October 2008 I made a deposit of Rs 10K by cheque on local bank which was debited next day in my account. Surprisingly, in the quarterly statement sent from TCS on behalf of CESC, they gave credit of the said amount after 6 days depriving of interest.
The matter was brought to the notice of CESC and TCS authorities without any result.
This is not the first case. In 2004 I deposited Rs 10K in CRES a/c with CESC but Rs 4K was returned as excess deposit after 3 months without paying any interest on the refunded amount.
CESC being a monopoly supplier charges arrear amount on all revisions but I find they are reluctant to pay consumers' legitimate due and senior citizens like me cannot do anything to recover.
You help is solicited herewith.
