ICICI Bank — Rounding off of nre fd interest

I want to know the rbi rule of rounding off related to nre fd interest for indian banks.
When we make a nre fd, icici bank shows in their website (Under deposits- view statement) the list of the date of payment of interest for the duration of the fd, and the corresponding amount of interest. The amount they show in their website is always rounded off to the nearest rupee. The interest amounts displayed are always the same for all the dates. I never asked them to do the rounding off, they did it themselves.
Icici bank shows in their website nre fd interest rounded off to nearest rupee, but after some time they are taking back the money that they paid extra due to rounding off.
Eg if the calculated interest is rs1000.50, they show rs1001.00 in the website. They pay 1001.00 four times, then deduct 0.5x4 =rs. 2. Thus for the fifth interest they pay (1001-2) = rs 999. However they display in their website that they will pay 1001, but they actually pay 999. They say that this is the rule. I want to know if this is really the rule.
I went up to 4th level complaint. Every time they said that what they did is correct. I asked them to pay 1000.50 every time and update the website also accordingly. They are not doing that. This is why i need to know the rbi rule related to rounding off of interest and what they are doing is really legal.
