Releasing calls!!!

I tried calling the call centre***) at about 11:45 and held on for about 15mins when I got through the call was released. I tried a second time when I got through I could hear people speaking in the background and typing and when I mentioned \I can hear them in the background"to my wife the call was released. I tried for a third time and held on for about 24mins when I got through the call was released. This type of service is pathetic and unacceptable from such a big company. I feel like cancelling my account and my 3 child accounts as well. These agents are giving multichoice a bad name and should be fired and not just get a slap on the wrist."""
