SBI — Unprocessed pan registration with the bank account

SBI is taking too much time or even not checking the request files online submitted by customers. I submitted my pan card number for registration few days ago and it showed pending at the beginning and now it shows unprocessed. I need to link it before the end of the month so I can apply for TDS refund. But it seems SBI will take more than a week to inform me that I need to submit again or whatever the next step is.
I am not able to visit my local branch which is the sole reason for using other facilities provided by SBI like online registration process but they seem to be of no purpose.
Thank you for listening
