Vastu Vihar — Regarding not returning my money and harassing me mentally

Address:

A P COLONY , GAYA, BIHAR, 823001

I invested my money in VASTU VIHAR, PH-03, MODEL VASTU NANO, BLOCK-C, UNIT NO- F/F-02, GRADE-LUXURY in 2013. They promised me to give possession of my flat in 36 months. After given almost 90% (426259 rs)of my money. I saw that only 20% construction has been done over there. I said them so many time about this.
Then in 2017 they said me that this construction will take more time to get it complete and influenced me to change this into their new project of ph-06. For this Again they took 1, 01, 000 rs and 4, 26, 259 which I given them already. Total 527259 rs they invested in their new project ph-06, unit no- SBE-29, block type simplex, grade-luxury, customer id-22518, city-Gaya type-2BHK.
For this project they promised me to give possession of this in 3 years and said that first they will make a swimming pool over there. After my several requests registery of that plot they had be done.

After almost 1 year I saw that they did not constructed anything over that project. Then I asked for this then they said that very soon we are going to start construction over there. Several time I asked about this but they said always same dialogue to me. Very soon.

Then in may' 2020 they said me that some dispute is over there on that plot. So again I have to switch my investment into their another project. I refused for this and asked to return my 5, 27, 259 soon. They asked this in written from me along with a cancelled cheque. Then I had given in written also with a my cancelled cheque on dated 08/07/2020. They said me to return my money within 30 days but they did not do this.
Mr Deepak Kumar, project manager, he is always taking time and harassing me mentally. He is talking like this that I think he is not afraid from anybody or anything.
So I request again that please return my money very soon.
