Totally Confused!

sadly disappointed with your level of service! my debit order did not go off, but I then paid the amount outstanding at one of your 4U stores, to which it took 2 days for my line to be re-activated. Then my line get's de-activated again, when I phone back the consultant tells me I still owe, however the previous consultant mentioned that the balance would be debited at the end of the month..now I am told that I actually owe more!!? the amount i paid was the amount the website said I owe.. now the website says i am in arrears by R0.00???? How does this work??? On top of that the consultant Maria Sanguweni was not helpful at all and even told me to watch my language when I said and I quote... \ this is utter ******* "..."""
