Consumer Redressal

I humbly request you to give me your help. I purchase my flat at Sahakar Villa, Kolegaon, Dombivli by paying full amount of cost & other payment demanding by Builder of Sahkar Construction, Mr. Uday Pandurang Mundhe (Mobile No.9223362555)& Mr. Sushant Tandel (mobile No.9223371888). Registration & duties already completed and after all payment through direct cheque and Bank loan (Banker :-Gruh Finace Ltd, Thane )they given me possession one and half year back. As per agreement they assure me to give us various facility but they fail. Now there is not authorized water connection available. After several visit at kolegaon grampanchyat they deny to give us connection. All concern documents given by builder to me at the time purchase (various documents and various permission of construction) available with me. Construction also not good, after 2 year building slap going to collapse. Terse PCC also very bad condition and no any road buildup for building. Now builder not pickup the phone.
