Imran — NPCI Blacklist

My vehicle no is TN38AQ0481. My fasttag was issued by SBI but now it is showing blacklisted. I have requested to SBI to deactivated. But when I crossed toll plaza's my vehicle number is showing blacklisted. I have contacted many times 1033 they are saying your account is showing minimum balance. What should i do? I am trying to purchase new fasttag from PAYTM but from paytm one msg was reflected as "vehicle blacklisted by NPCI"

Kindly rectify and do the needful so I can cross plaza hassle-free.
If any qury to ask me pls can contact [protected].

Thanking you,
