Sbi Fastag — fastag rfid tag closure

Since 5th jan 2020 a email was sent to sbi fast tag team for the closure of rfid tag 34161fa[protected]da0 for the refund of security and balance amount. The standard time limit is 4 days to close the tag and refund the amount but till today i. E. 26/02/2020, more than 52 days have passed and several requests and reminder mails sent but no action is taken. I sincerely believe that it is another way of sbi to harrass and cheat the consumers.
