Hello AFF! It's me again
As promised, here's an update on what happened to my account...
I waited out my 21 days of punishment by Qantas after which... nothing happened. Account still locked and zero correspondence from QF.
Considering I had 4 J award tickets booked I thought it would be best to stay quiet just incase of an account closure in which case I would most likely lose my points and my flights. So I waited some more.
This week curiosity finally got the better of me and I called the number provided in the email.
After explaining to the agent that my account had been locked due to some transaction through the QF Mall, I was placed on hold. 5 minutes later the agent got back to me and apologised for any inconvenience caused. He explained that retailer X (not going to say which one.. sorry) still credited points even after a refund or exchange had taken place within 30 days, which had been the case for me.
The agent only referred to 1 single transaction which caused my account to be flagged as "fraud". He said "take this fraud thing lightly as it's definitely not your fault that the points still credited". I told him it was poor form to just freeze accounts and provide zero correspondence as to what was happening almost 1 month after the supposed 21 day waiting period. In the end he told me no points would be taken back (since the transaction he was referring to was a simple exchange of an item) and offered me 10k QF to compensate for any inconvenience caused which I think was a satisfactory outcome to the whole situation.
