Dear sir,
I deposited my money in 2008 in abode bind. Later in 2012 Sahara agent forced me to convert it in SAHARA Q SHOP. Again in 2018 I was forced to convert in Sahara GOLDEN 24 POLICY. Now my policy is matured in May 31, 2020. But SAHARA AGENTS AND Manager again denying to give money. Please let me know how can I get my money? Should I go for Legal notice to Sahara because it's clearly seen that they keep on delaying to give money.
