Karrm Infrastructure — nobody gives proper information at the karrm office

Address:

Mumbai City, Maharashtra, 400094

My name is David Peter, I have booked a flat along with four of my friends in Karrm Pachatva Phase - 1 & 11. We are keep on paying the EMI to Karrm and they make payment to bank. We have submitted three to four times the required documents for shifting the bank loan to another bank but Karrm office keep on calling for submission of documents. We are called for their office for submission of documents. We wanted to know from which bank we should obtained the certificate to claim income tax rebate on the interest paid by us. We have booked the flat in 2015 and till date we are unable to claim the income tax rebate.

Please guide on this.
