Unhappy with poor service

Two weeks back I sent a message on your WhatsApp for someone to assist me payment arrangement as I switched jobs and explained to them I want to pay double in the following month due to the fact that I recieved training money for the under the new Job

This guy kept insisting or pretending not to hear me that I want to make an arrangement not settle the account

He persisted on settling the account and seeing that I was buying to his story he hung up the phone. I texted him back and asked are you hanging up the phone now because I asked for a payment arrangement? His name starts with a W (sounded coloured) called me on *** please investigate the call history

It's unfair that I did reach out only to find an employee that represents you who did not want to assist me

Now you guys have added fees on my Wonga account which is R9 100+ when my Account balance was R7 600 rounding off just two weeks back because of missing a payment which I tried to arrange for ? How is this possible that fees can be that high to begin with? This is just day light *******
