IIHT — No fee refund

I started the cloud computing course in feb 2013.it consists of 4 moules.They told us that the course is for 6-7 months.Now it been more than an year and they have only got completed 2 modules. Now when I talk about getting other two modules completed they just gives me an excuse.Sometimes they say we don't have the trainer or sometimes they say that we will let you know when it will be started.now when I talk about refunding the money they straight away deny that.Now I don't know what to do.They are fraud and same story is with other students as well.Very depressed and don't know what to do.
