[Solved] Can a higher rate of interest on any Post Office Small Savings Scheme be considered a Benefit?

Is the interest provided by Post Office on its Small Savings Schemes construed as a benefit from the Govt.?

The Dept.of Posts is now claiming "Benefits means the higher interest being paid on these schemes".

Post Office Small Savings Schemes are an investment instrument / financial product and public is investor.And in order to attract investment they declare higher rate of interest.

So how can the Dept. of Posts now consider the higher interest to be a BENEFIT when it is actually a return on investment?

Especially when no such communication has been made at the time of investment?
