Damaging good credit records!!!!!!!!

I just checked on my Direct Axis Pulse App now and apparently I am paying R63900.00 per month on my MTN contract (which is incorrect). I pay R639 per month. Can this be rectified immediately as this has damaged my credit rating significantly. I hope this will be sorted out urgently because I am doing a credit application for something next month and if declines due to this I will be taking this further. Please get back to me ASAP!!!
