The one you did is the only way.

As far as my observation is a concern, tickets related to signature campaign payments are being ignored since then even during the time when they are active and paying their participants here. I'm part of their campaign way back 2015 and also have minor concerns about sig payment but never of my tickets were being responded.

However, even I never heard of a signature campaign-related ticket being answered by them, some of my minor exchange related issues in the past are able to handle. That gave me a conclusion that they never care for any sig campaign-related concerns.

Anyways for your reference, during the time when they are still active here in the signature campaign, troll box moderators are the one who fixes the magic button for transferring campaign payment to wallets. Yes, they will notice anyone who has a concern about it. However currently, if I'm not mistaken, users should have an active balance of BTC0.01 (or BTC0.02?) before anyone can send a message to the troll box. In the past, there's no restriction like that.
