Amazon's strickingly bad problem solving skills

I have struggled for 2 days to just update my number. Ive spoken to numerous people from all around the world ****terally) and none seem to be able to help me. All they can tell me is to recreate an account which will unfortunatly lead to all my purchases being lost. Only once Ive spoken to every possible person on this planet Amazon South Africa realized my account was with them, as if its such a shock that a person calling from South Africa will not have an South African account. I have now had a conversation with a lovley lady and I am fully aware that this will not be the consultants fault, it is the company. She has informed me that my account could be linked to Australia and that she does not have the number for the autralian department. What does that mean, more hastle and more money on airtime to be able to speak to people from overseas. AND MY ACCOUNT WITH R3000 WORTH OF BOOKS IS STILL LOCKED!!!!!!!
