ZEP Nightmare with Payment not allocated to application

It has been a nightmare for me with this application process.. I paid for my application on the 11th of Oct online trans number ********** 9 and till date can't schedule for an appointment as the payment is not reflecting on my application, I was informed to wait for 3days, I called again as it was Day 4, I was informed to email my pop and details to ********** on 16.10.2017 and would receive a response back in 72hrs, the 72hr turnaround passed, called again, another agent said I must email zepqueries and they will attend to my emails, I have been sent to pillar to post and no reference number and no response on emails, agents can't assist it's as if their all given the same line to say when people call,

I would like my payment to be allocated to my application, it's 2 WEEKS NOW they can't be excuses to say emails are being attended too and we are dealing with large volumes, how do i even know it's being attended too with no acknowledgement of receipt, I am going to MAKE A BIG NOISE over all platforms over this, expecting a response Asap
