Stars Multipurpose Cooperative Society Limited — Non payment on Maturity

I have invested in Sahara India in 2012 for min 10 years on good returns but in Dec 2017 the agent of Sahara India contacted me to transfer entire money in Super BB scheme of Star Multi Purpose Coopertive Society Hyderabad that after 3 years in Dec 2020 money will be refunded as Sebi has taken certain steps against Sahara India which the agent did not inform me. Now after maturity agent is not informing any thing about refund and only telling that sebi has seized the money in sebi sahara account. But sebi has taken money from Sahara and not from Star Multi Purpose Coopertive Society Hyderabad so how to get my money back
