State Bank Of India [SBI] — tds deducted but not shown in 26as form

My father have an pension a/c in sbi, railway road tohana, distt:fatehabad 125120 (Hry). The bank had deducted the tds rs. 8746 but not shown in online 26as form. Due to this i could not fill the itr/refund claim. I also approached to asst manager to provide the form 16 but he says form 16 is not generated and our bank ca did not pick my phone.
Is this a right answer.
In view of the above please do the needful that i had also skipped the due date of return 05 aug 17
