Tata Capital — foreclosure/pmay/delays in original documents handover

Address:

Bogadi, Mysore, Karnataka, 570026

Hi, we had taken homeloan from tata capital. They didnt give us pmay scheme benefits and very delays in phase loan allotments, so decided to go for b. T.
Here also upon foreclosure of the loan, they are playing to give back the original documents.
Stating un valid reasons.
Today they called us to handover the original documents, where as 6 documents are missing out of 12 given under lod.
Please suggese the possible resolution with compensation.
