808 nr on hold for more than 30min and no answer!

I've been trying to call the number 808 to switch from contract to prepaid since the 17th of june 2015!<br> Everytime i wait more than a half an hour and no anwser! so I decided to to mail them! and no response either!!!<br> and when I go into a store they tell me to phone 808!!!? but how the **** should I do that when there is no awnser, EVERYTIME!!!!! <br> This is by far the most horrible service I have ever gotten from any company! If they deduct money from my account this month for the contract I do not want and a contact that should be expired since the contract peroid is over! I will take this much further!
