HORRIBLE CUSTOMER SERVICE

I am at my wits' end with Standard Bank. I have been running up and down between branches since 1st September 2015. I have even called their complaints resolution center on 12 September 2015 to no avail. My problem started when my account was incorrectly debited for a personal loan which was paid up on 24 July 2015, on 1 September 2015. i have been requesting a refund ever since and to date i have not even received a phone call from any representative of Standard Bank. 6 weeks and a long list of reference numbers later, I believe it is time that something gets done about this PATHETIC service I pay Exorbitant fees for!
