Spectra India Housing — Money blocked in spectra need refund

Hello there,

I am Shaik Lalmahammad purchased 240 SY plot in Spectra Galaxy, yadagirigutta under Emi basis. It's been 4 years there is no development in the project which I selected when I am requesting my money company is saying they will deduct 20%. I took the plot @3500/ sqryard now company is selling 6000/ sqryard. This is not at all fare. All these years I have paid 45 emi's another 5 emi pending instead of giving interest to my investment they are saying they will deduct.

Please help me.
