Qantas ducking and diviing or not paying refunds or credits!

I have been contacting Qantas regarding a flight cancellation since March i have sent many mails - long delays in responses Each mail giving different instructions Then finally told more than a month ago that my refund would be paid into the credit card account (Amex) within two weeks Nothing happened. The local contact number is impossible to get through to - no toll free number. After a 3 hour call (We are very busy please wait response) i finally got through to a human being. After holding on for nearly 3 hours I got through to someone who said the local office cannot action refunds. I held on for ages while the operator cross checked my details and finally went through some steps as directed by the operator., I logged onto the qantas.com Site as directed and followed her directions which was very unclear as it showed 4 flights to choose from despite this being a single booking originally. reference SUQ99P at this point the call dropped or I was cut off. I chose the first flight for each of the options given for myself and my wife and received the two automated response with reference numbers A further 7 days has gone by with absolutely no further action being taken. I am convinced that Qantas is doing their best to avoid giving a refund and are being deliberately obstructive. Please can something be done so that I can plan my long delayed Australian trip!
