Can a life insurance company increase rate of premium arbitrarily during policy period?

Suppose I take term insurance (for life cover) for 25 years from some company since I find they charge lowest premium. Can it happen that the company hikes the premium rate arbitrarily after 5 years, to such an extent that I find the rate is more than the premium rate of some other company I ignored earlier. Is it better to stick to public sector insurance companies or are they as good as private sector companies?

What advantage does LIC’s Market Plus “without life cover” have over a mutual fund?

I took LIC’s Market Plus without life cover last year. Since this policy is without life cover, isn’t it like a mutual fund?

If it is like a mutual fund, why do they have so high premium allocation charge of 16.5%?

Since, I am just 23 years old, I don’t want to continue it for 20 years. So, if I surrender it after 3 years, I will be at loss, right?

What is the best way to get out this policy with as little loss as possible?
