Unsatisfied customer

I am very unsatisfied with your service. I had changed banks from Capitec to Standard bank and was given a confirmation of new banking details for our payroll department. I handed this details in on time to ensure that there are no issues with my salary. To my dismay, your staff allocated the incorrect account number on the form, resulting in it bouncing back and now i am unable to received my salary due to this negligence. Your staff's negligence has also resulted in me having to take time off from work to come into your bank as no one can assist me and rectify this telephonically. Did I make the wrong choice by leaving my previous bank????
