non-Delivery of Contract Notes

#1
Are there any rules regarding the broker delivery of Contract Notes?
My broker purchased 10k shares of RNRL and sent me a contract note for it. When I went to close my account, he claims that he sold it but I did not receive a contract note.

Also, I suspect my broker maybe manipulating contract notes. How do I independently verify/validate the transactions? Can we request BSE to give us a transaction log? If so, what is he procedure to make the request?
