Not professional

Good day. My name is Winnie Nkadimeng from Witbank and have been a customer with Autopage for years. Since last year I have been having problems about Autopage not billing my account correctly. We tried to solve the problem and one of their consultant by the name of Pertunia assured me that my account is up to date as I was owing an amount of R1340 of which I've paid sent proof of payment to them and to Nudebt and according to her I don't owe them anything. Now since last week my phone is being cut off without any warning and when I call in to query about it they apologize as they can't understand why my phone has been disconnected. Today I called in again to find out what the problem is I got hold of this lady she was very rude now she tells me I owe an amount of R1690 from last year. When I tried to explain to her that it was R1340 of which I've paid she was very rude to me and she put the phone down on my ear. I feel that it's unprofessional and very inappropriate especially that I've been a customer with them for a long time. I currently can't use my phone and nobody is willing to assist me to solve this matter.
