Home buyers taken for granted

Agent sold me a house that had i cannot move into. what steps can i take to solve the matter. 1.The bond has been registered in my name 2. I am paying the bond, the title deed has been issued to the bank 3. The seller **** about ownership of the property(there's an interdict), because there's other children who are Beneficial's of the inheritance 4. Its a deseased estate 5.The agent, conveyor not updating me of possible steps 6. I cannot move in to the property because of the other inheritance beneficials 7.before the payment was made by registration attorneys, I notified all parties that the house is vandalized and for some reason the payment was processed. How? And why? Cause this would have saved me from all this mess. I need standard bank to help me fix this mess.

I tried to call standard bank mortgage department to assist, but I get sent from Pillar to post. I have asked to speak with the manager and it's either they are unavailable, will return my calls, in a meeting.
