State Bank Of India [SBI] — form 16

Dear sir, i am an ex service man drawing my pension from sbi puttaparthy br through savings bank account [protected]. Though i submitted my pan details, so far i didn't get form 16. Please do justice. Along with my life certificate i have submitted my pan details also. On 12/07/2017 when i went for my form 16 i was told by the branch officials that my form 16 has not been received by the branch due to non availability of pan details. Since then i am approaching the branch officials but till date i have not received my form 16. I am worried about the delay tactics of the officials. The last day for filing it return is 31 st july. Please advise me what i have to do. Thanking you sir.
