How to get a response to refund request to last.fm?

Question

December 13, 2012, last.fm announced that they would be discontinuing their radio service in several countries on January 15, 2013, and that customers could request a subscription refund. I did so the very same day, because the radio service is 90% of the reason for buying it (the other being the event announcements). On January 16 the last.fm client could no longer play their radio, and I have still not heard a single word from them. Has anyone had more luck with this, and perhaps any tips to get through to them?

Answer 1

I started a thread on the assistance forum on 26th January.

The answer from a LastFm team member was:

Next week, I believe.

So I guess people will get refund in February.

Answer 2

After following the advice in @RenaudDumont's thread I posted the following support request:

Username: [removed]
Last payment: 19. Sep 2012
Paid for: 12 months' subscription
[removed] Transaction ID: [removed]

What is the status of my refund? I requested it on 13 December 2012 and I never heard anything back.

Anybody else having this problem should probably do the same. I wonder how many thousand they've effectively swindled so far...
