stop my phone

I did do a payment on the 1 Oct 2015 on my account today they suspended my account to they say my account is in arrears the morning of the 1 Oct 2015 i did phone *111# to get my outstanding amount the amount that the computer told me was R1236.36 that was the amount i have paid. Today when i phone my account is suspended due to i still have to pay R250.00 then they will reinstated my phone i refuse to do the payment before the end of the month because on there system it tell me the amount and i have pay it. So the first lady told me my account will be reinstated after an hour but after an hour nothing happens i did phone again and then the lady told me i have to fax the payment then i tell i do not have a fax masjien and that there service is up to ****. Because they can see on the system it is been paid. So i really think there computers are totally wrong. Then after 10 min my phone is fix after i told the lady i will put it here. i need some feedback about your bad service.
