Website: www.sbimf.com/en-us

I purchased nav's in 2016. Now i want to sell my all nav's but sbimf executive told me that i can't sell out for next one week since last two week he is telling me like that.
On 21st apr i went to him give him application for redeem all nav's, he assured me that money we be transformed within 2-3 day in account but he din't then i again went to him on 25apr and again i gave application but he could'nt. Then i again went to him on 1 may then he told me that i can't sell out for next one week. Because auditing is going on in their firm.
I immediate require money.
