SBI Ppf Account — Not crediting amount in mids of 5yrs extension term

With reference to my PPF a/c :-[protected] ( CIF no:-[protected] )
I would like to inform you that My account was opened in year 2000
( Matured in 2015 & it was extended in to another period of 5yrs i.e 2020. I continued depositing further in my account till March 2022.(My last updates till March 2022 )

Now for financial year 2022-23 when I tried to invest/deposit online in my PPF account the amount is NOT GETTING CREDITED in my a/c . I approached my HOME BRANCH,
they said that their system is not accepting FURTHER DEPOSITION either by cheque or online . Their system sends message that FURTHER EXTENTION is DENIED .

Even if FURTHER EXTENTION is DENIED it SHOULD NOT BE in MID of 5 Yrs TERM i.e 2020-25.

KINDLY RESOLVE THIS PROBLEM of mine, so that I can further make deposition to PPF, atleast till 2025.

LOOKING AHEAD FOR IMMEDIATE RESPONSE
