How to claim tax benefit of employee fails to make the salary more tax attractive.

Hi,
I am an employee working in a private company. my employer has not provided the following benefits in my flexi pay which will help in claiming more tax benefit :
- Telephone / Broadband Allowance,
- Gadget Reimbursement,
- Newspaper / Magazine Allowance,
since my employer has failed to make provisions for the expense mentioned and we understand there is a provision in Income tax where the employee can claim the tax benefit to an extent there is an expense under the mentioned heads.,
Can you please suggest how can I claim those benefit and doesn't become the victim of my employers ignorance ? please suggest. I have written to my employer about the provisions but looks like going to the deaf ears.... please suggest.
