Bad Online Payment System

On the 28th of November, 2017 i made an online payment for my VISA application and it has not reflected on my account up to now. i have sent several emails and spoke to the employees at VFS about the matter but have been thrown from one branch to the other. I don't understand how an online payment could lead to so much confusion when its linked to my application. I have gone to the extend of forwarding them the proof of payment showing the transaction and the online ticket number. This has led to more frustration due to the incompetence of the staff at the VFS ZEP customer service.
