Non-responsive Call centre

on the 15th of March I called the 808 number to change my billing information. I phoned 4 times and was cut-off 3 times while waiting for someone to pick up the phone.<br> <br> I changed my billing details and was told that the outstanding money would be deducted from my new credit card before 12:00. I later received an sms that I need to pay the outstanding money immediately. <br> <br> I then called them back to understand what this sms is about after I was told something different earlier. Again I called the 808 number and was hanging on for over an hour without anyone picking up and I was cut off 4 times during this time where I had to call back. Eventually I decided to rather chose the value added services option and someone picked up immediately. I then told them that I am not happy and that I need to speak to someone that can assist me with my query. I was told that I am through to the business division and that they would put me through to the correct division. I was put through to the \correct\" division and was basically said they cannot help me due to a system error. I requested to speak to a supervisor and I was told that the supervisor will not take my call. ..."
