If the centre is anything like the qantas money call centre in the Phillipines, it will be a disaster. I have called and emailed them over the last 2 years about incomprehensible charges and even more baffling explanations for the charges, with nil satisfaction. Since my last conversation in March with a very nice,but clueless, person who promised a response "within 48 hours", I have heard nothing. But as they seemed to think I owed them money when they last emailed me (not possible), hearing nothing is the second-best response....
