Why am I being charged a pro-rata of R1000 for three days on the free me service of R100?!!!

Why am I being charged R1000 for pro-rata of three days for a free me contract of R100?

That make sno mathematical sense . You have practically charged me double my installment, how guys? I have two routers with that I took with more than three pro-rated days but never have I ever been charged double. Hzow did you get to a Septemebr balance due of R2100 for a contract of R1099?

Please do not feed me lies. I am not in the mood. Rectify that deduction or I will go to the ombudds. There is no way that I am being charged an extra R1000. It makes no sense at all.
