packet switched data *******

I have 3 numbers with this useless establishment all of which are meant to cutt off when the limits are reached which used to be the case.I suddenly have crazy bills on 2 of my numbers starting around Oct 2015. I have sent numerous emails to the customer service and been given the run around and told to call 808 - good luck with that as they are always \offline\".<br> I went to Northgate and was told the accounts are not blocked and when I asked who changed this no one could answer. One phone was through Northgate and the other Clearwater both MTN stores to my knowledge but Northgate tell me to go to Clearwater. I am done running around and will cancel my debit order as you are ******* ! Perhaps some one will have the courtesy to call me when you dont receive your money !!<br> "
