Again on 12.12.20 two days later another Rs:230 was suddenly debited stating "debit adjustment.I raised complaint with SBI FASTAG on 12.12.20 itself, FOR WHICH THEY RESPONDED ON 18.12.20( AFTER SIX DAYS) and replied that they raised charge back which is to be responded within 16 days.But to my dismay even after 20 days there is no response either from SBI FASTAG or from other party who debited illegally.REPY OF SBI FASTAG TEAM IS APPENDED for information.
