Unhappy and disappointed

So in December I took out a new load and was advise that my old monthly installment will be canceled and the new one would start on the 27 December with prorata added. What a shocker when a double payment of almost R 8000 was deducted from my count. Really the amount should of only been half. Now how do you except me to pay my other bills because you deducted a double payment🤬. I have been trying since Thursday to try and get this resolved but no luck. As your phones either does not work or when I eventually get through the line gets cutt off. It is funny as I have been a client of DirectAxis for a while now and this is the first time that I have had so many issues from the word go of taking out a new load. Please can I get answer soonest. I have also send a email on Thursday but wow your turnaround it is taking forever. Really unhappy
