Compliment On Research Infotech Defamation

This is regarding a brokered calls on intraday futures. Research Infotech coordinator called me and offered a service, stating that they will give calls on daily basis. Also assured over call that 80% of the call will get success at first I am not concerned but after few conversations I accepted and as of now totally I have paid 24000 out of 150000 for the service. They have provided calls which is 95% failuer rate where I have lost arround 60000 in 5 days. They have not provided any invoices also for my payment. When I enquired about my loss they told their technical team is not good so we will changing them in a while. Which means they know that they cannot give calls. By knowing that only they have cheated me by fake promises.
