I am also very surprised to hear these problems with
MP3Fiesta. I've been using the service for the better part of 3 months and have never had to wait for balance updates (about 10 min. wait at most). I have had no problems downloading, which is simple once you master using FlashGet. The only time I had a problem with an album, my money was refunded in a day or so and the album was pulled almost immediately (and later replaced with a working version).
Very surprising to hear these complaints.
