Telkom Bill, Not Called and No explination

Good day<br> <br> I have had many disputes with Telkom, and most of them have been settled quite well. My last dispute has been handled in a way that would make anyone upset and angry. I have been dealing with Hanlie Blumenthal from the disputes departments. After her first call regarding my dispute and after me showing her that Telkom owed me more than they refunded, she said she would look into it. I went through the bill step by step and basically showed her what she couldnt see. Eventually I was happy because I assumed I would be properly compensated. I always agree to pay what I owe but I refuse to pay cash for a huge bill as Telkom doesnt do cash refunds. <br> <br> Hanlie promised to call me and explain, after waiting for a week and after me calling many times and many emails, she says she cant call me anymore and can only email.<br> <br> How am I supposed to understand what is going on through email?<br> Sending me excel sheets to confuse me makes things worse and what I have to say gets lost because I dont understand what is going on?<br> <br> Is this how telkom sorts out disputes?
