Bad service

<p>I am so ****ed, I am changing my network I just can't, yesterday I bought power hour and Just for you minutes the ones that last for 3 days, today when I try to make a phone call it doesn't allow me and when I check the balance it says I don't have any minutes available how? I tried calling the call centre but they giving me attitude, I spoke to the supervisor who couldn't help, I asked to speak to the manager on duty she refused. I did my own calculation I was on the phone for 125 minutes during the day and I also made a phone call after 12 because I have night shift minutes. Where did my 174 minutes dissappear to? </p>
