Easy pay problem

I have been trying to pay my account via easy pay since yesterday today im on the phone with supersonic and they telling me the easy pay number is wrong but ive been using it for months how does that make sense and they keep transferring me to different departments and nothing is happening. When i go on the portal its saying im in arrears with over R5000. Thats 15 months behind but ive been paying prepaid since that time so how is it in arrears when the wifi has been going off after 28 days and i had to buy prepaid everytime im so upset and im so tired i feel like cancelling and going to another network but that will probably also be another long story. You guys need to sort out your account and get employees that help us better. Because you are losing customers
