Customer Care Waiting Time

I called the customer care number (808) and waited for about 11 minutes and was cut-off due to bad signal. I called back immedaitely and waited for a further 9 minutes before going into the ba*****t parking lot, where bad signal cut the call again. I called again for the third time and waited on hold for 16m23s before an agent answered my call. This is not the first time that this has happened. A few months ago I must have waited for 15-20 minutes before an agent picked up.<br> Poor customer service.
