Suspended outgoing calls VERY UNHAPPY

Hello,<br> <br> In August 2015 my contracts were expired and I arranged to terminate one of my contracts but I was advised to do so in September which I did. I had an upgrade done on the other number and was billed for both numbers.<br> I then called on the 11.12.2015 at approx.12.40 enquiring why I am still being billed for both numbers and she seen that I have made arrangements in Sep to terminate the number and I cannot be billed for a number I am no longer using and that I need a refund as she will notice that I have not been using the number but someone else has that number ,she said that she will arrange/ make a note for the bill to be amended and the refund done.<br> I received another bill in Dec with the same amount and I called again on the 11.01.2016 at approx. 10:48 I spoke to Yolandi and explained the situation again. Instead she told me about 2011 and 2014 statement and I then realised there is a misunderstanding and that I need to speak to her superior. She told me to hold on and then upon her return said that he is in a meeting I requested he call me back and I have not received a call since then and I am very unhappy with the service as my phone is now suspended
