WORST SERVICE EVER

I app**** for a personal loan online on 30 December 2015 which was approved but because of the festive holidays I was unable to submit my supporting documents, then on Wednesday the 06 January I submitted my supporting documents at the Rosebank Branch. I have been calling the personal loans department since I have submitted my documents and every time I'm told my application is still at verification. I wonder how long does it take for a bank to verify their clients details. I'm highly disappointed in the level of service my application is getting.
