ULIP plan from Reliance Life Insurance?

I have ULIP plan from Reliance Life Insurance. I have bought the ULIP Plan in year 2006. Now I wanted to surrender it because it is not giving me good return; also the charges are very high. I have read in one of the article that "If you want better return from ULIP it is adviced to stay invested for longer period as 10 years or more." Please advice what should I do know?

First - Insurance is not for investment.
Second - Keep insurance separate from investment.
Third - Insurance is, if something happens to insured than what ever liabilities he left over will be taken care off.

Anyone thinking to invest in ULIP Plan than you must give ULIP at least 10-15 yrs because of high charges initially. Your advisor is saying right.
