Rude consultants! Line De-activated!

I have just made my payment at Nedbank for my Cell C account but their ****** *********** staff refuse to re-activate my line and worst part is, THEY KEEP HANGING UP THE PHONE IN MY EAR!!!<br> I am being told that the amount paid is short BUT nobody can tell me what the amount I am supposedly owing is for! I actually called HELL C from the bank from a friend's phone to confirm banking details as I had forgotten my phone in the car, they gave me the details and confirmed the amount to pay as R380.00 and that is the same amount on the sms they sent me as well although the phone was in the car, this amount was given to me verbally. Now, when I call I am being told that I should've paid R419 but nobody can explain what it is for. They confirmed an amount to me over a recorded line and still sent it to me via sms! therefore I demand that my line is reactivated NOW!!! I AM SO SICK OF HELL C, THEIR *** SERVICE AND THE CALIBRE OF ***S THEY EMPLOY!!!! I NEED MY LINE WORKING IMMEDIATELY!!!
