Blocking my phone for the 2nd time this month

I am really frustrated, Friday I had to spend over 20 minutes over the phone as my line was blocked. I then received an apology sms to say they had a system problem. This morning I tried phoning again and I was then heard my phone was blocked again. I have also requested my itemised billing and this is also a mission to get. What bad service, then these sales persons from autopage phone me every freekin day to upgrade my two accounts with them... hell no....
