Purchased property under sarfesi act- SBI misguided us

1. I participated in sbi auction. For the property which was under symbolic possession under surfaesi. 2. Paid EMD , I was successful bidder. Paid all the payments. In fact 75% last payment I paid a week early as Insisted by. Sbi authorities as they were visiting city and can execute sale certificate. 3. Then after full payment they started neglecting, That thrs some stay on property case is in Patna high court. They visited city and kept a sale notice on the property and mentioned for sale contact SBI, even after full payment. 4. They asked us to wait till the order and gave weeks, few days vague commitments. 5. After waiting around 20 days of full payment we wrote email to all authorities about this but there was not reply. But after 10 days of email the concerned officer asked us to take sale certificate but he said physical possession will be given later. Without clearing the reason. For anything the sbi officer asked us to talk to law officer of SBI. 6. After 15 days of first email we wrote reminder. Mail to a the authorities and they sent sale certificate 7. Now I dont kNow whom shall.i ask the legal status of property, or when shall I get possession or the title is clear or not. Sbi lawyer and officer are just giving vague answer s. No clear information. That too verbal. Nothing in written How shall we proceed? They say that buyer has to check everything before buying it. But bank is not giving any information. When we asked for the high court order they said we can't give. I thiNk they are just fooling us
