Recent problems with leaderboard – Foursquare Swarm: Check-in App Review

For the past week, Swarm has been deleting all my coins from the leaderboard. At first every other day, then more frequently and now it wipes out my score several times a day. I contacted the developer for support (a very difficult process in itself) and the problem was reported as verified then fixed. But it isn’t fixed! I have having to write a bad review for an app that I use every day, but I don’t see any other way to get the issue resolved.
