Yellow the end...REDICULOUS

<p>I am a contract customer with an open-line contract. Yet for some reason I am not able to make any calls. It keeps on saying that I have insufficient airtime. I urgently needed to make a call and even went so far as to load airtime....which also did not work. I have spoken to 8 agents and am holding for the 9th as I am typing this. NO ONE can resolve the issue. This is absolutely ridiculous. In addition, I have requested twice to speak to a supervisor in the call centre, and after holding the line on both occasions for 10 min I hung up. To make it worse, the music you listen to while holding is the same music that was playing when the Titanic was sinking. What am I supposed to do to be able to make a call on the contract which is paid monthly without any issues???????</p>
