Hi all,
just to give you an update:
After 5 Calls to the Brazilian Agent (finally with a correct number) and at least the same amount to TK we've now been able to get a full refund. It'll take 60-90 days until the money is back, but that's fine.
BTW, I forgot to mention the ticket also has shown this:
"NO ADC TO DUE SCH CHG TK15/19MAR"
It was just frustrating that TK kept saying "yes you can get a full refund" and the agent kept denying and even said "TK said we can't refund because the changes are to small"
Anyway: Ende gut, alles gut!
I know... it's a shame. But we'll jump on the next good fare later this year!
