Uco Bank — Excess Home loan Interest being charged

Dear Sir,
I have taken a Home Loan from UCO bank vide the above mentioned Loan Number on a floating rate basis and have been regularly paying my EMI.
But when I am checking my account status today, I am finding the rates that have been applied are not matching with the rates applicable at Uco Bank at those times.
For example, the current rate is at 9.70% (as on 5th Oct, 2015) but my statement shows Rate of interest as 10.75% .
The following is downloaded from Intranet, which shows ROI from 2010.

Base Rate Date
9.70% 05th Oct 15
9.95% 01st May 15
10.20% 11th Feb 13
10.50% 01st May 12
10.75% 01st Aug 11
10.25% 12th Jul 11
10.00% 05th May 11
9.50% 01st Feb 11
9.00% 15th Dec 10
8.50% 05th Oct 10
8.00% 01st Jul 10


I had approached the Branch manager of the said Branch (Park Circus Branch- Kolkata 700014) who after much follow up corrected 1 month wrong interest .

But the error is happening from a period of 10-15 yrs.

Considering this difference, I would request to check the same and get back to me, within 7 days, on why the difference and what corrective measures has been taken to get this corrected.
I have been following up for over 2 months now with your local office but of no use.
