BookMyBai — asking to sign wrong document

Address:	Mumbai City, Maharashtra
Website:	www.bookmybai.com

Before making the payment, Bookmybai.com negotiated to below in spite of their policy:
1. They agreed for a charge of Rs. 4000 Plus 18% GST and we maid the payment of Rs. 4, 720
2. They also agreed to give a replacement when we shift our house within city within 6 months.

Now while making the agreement they are not agreeing on these 2 point and asking us to sign on wrong agreement.
