Club Jetstar

I have had nothing but problems ,with what I now consider to be the least useful thing that i have ever purchased. I find the club so difficult to navigate, that my recent booking with your company for an overseas flight was completed without the use of my membereships, as i had such difficulty gaining access .Perhaps it is a glitch,perhaps I am expecting too much I would have thought that a membership would show me my details flights ..and my vouchers Unfortunately that doesn't appear to be the case thank you Regards Len
