Employee of sbi life insurance called me up and gave following information for sbi money back policy(15 yr max term)

For sum assured of 3 lakhs, 30 K premium, with total 115% of bonus on 15th year (10, 15,20,45 on 3rd,6th,9th and 15th yr respectively) plus 10% "guaranteed" cumulative interest for amount invested.

Also this can be surrendered on 4th year with benefit of 1.5 lakhs (1.2 L over investment of 90K for 3 years and 30K bonus)

However the brochure doesn't guarantee 10%, it doesnt speak anything except "bonus". Also it says policy can be surrendered on 4th year but appends it *conditions apply.

Any expert can throw light on it plz? is this valid and truthful information or fraudulent sales/marketing trick of trapping money
