Flight cancelled no flights available until the next day

I got to the Wellington airport extra (22-11-18) early to allow for any mishaps, waited in line for an hour, got to the counter to have the nice lady tell me the flight had been cancelled and they could get me on a flight the next day. Given the conference I needed to be at that day I declined their offer. The clerk told me to go on line regarding refunds. I had to spend a lot of time on line searching and then on the phone to get a case number, otherwise, so I painfully learned, JetStar would not accept my e-mails. Also other airlines text to indicate a change so passengers can make rearrangements, but apparently not JetStar. I am still making my way throug this mesugganah and am paying extra to consult a lawyer. For the amount of money I have spent on getting another airline ticket from some other airline (AirNZ!) and the loss of time, I could have flown to Hong Kong. Never again JetStar.
