Calling up can work and it can fail dismally.
I needed to change a booked Velocity award flight on EY.
So I rang Velocity and got one of their Philippine based CSAs who turned out to be worse than hopeless. After 75 minutes despite checking online repeatedly and finding available seats - she kept insisting there were none. So finally booked onto 3 leg flight to get to MUC and when charges quoted I knew they were wrong and said so. Ask to speak with supervisor etc - no supervisor available (false but normal try the last two years) istead she says she'll send the confirmation through and I'll see it is all correct and HANGS UP.
Email arrives - ALL WRONG. Wrong class, charged 4x for the one set of flights (fees & charges). After counting to 1,000 I ring again and get an 'angel'.
This lady knew her stuff, asked why I would route via Melb with 4 hour layover when two different direct flights were available to MUC. I then mentioned that I had asked to book F and her reply was well the seats are available for F as well.
Then she looked further into the incorrect booking and confirmed that we had been charged, for some reason, four times. So she said she'd have to get a supervisor to look into it and refund the amounts.
Less than 5 minutes later, all booked in F for flights to MUC, 1A & 2A allocated, emails received (while still on phone to ensure spellings etc all correct). Such a difference.
Moral of the story HUACA - just like the roulette wheel sometimes your numbers come up.
POSTSCRIPT
The reversals were not done correctly, and one set of F&Cs were not refunded for the cancelled flights. 5 attempts, 7 months later and around 3.5 hours on the phone to the Philippines told there is no error and case closed. Once the 'case was closed and marked refund already paid' and they did not bother to contact me. I found out ringing after an extended delay in hearing from them.
I even sent a copy of the cc statement showing all the transactions listed for VA Gympie. Still - no refund due. Common response was fault due to your cc provider - call them, it's nothing to do with us.
So I asked for the details of each transaction they claimed had been made, including the 23 alphanumeric reference number. They refused to provide.
Finally rang the VA Company Secretary (chief legal officer) directly late last week with a raft of issues (such as refusal to provide copy of recorded calls = breech of Federal Privacy Legislation). Next morning a call from the Philippines - You were over-charged by $X,xx_ and a refund will be made to your card ending in YYYY later today. You will receive a copy of your phone call within the next 20 days....
