Sorry to hear that
Gear store has been very unresponsive since Treehouse was acquired by Thinkgeek (thinkgeek was acquired by GameStop, we all no how bad GameStop is).
The online gear store was manger by thinkgeek and the gear store at PSX was managed by Sony, so contacting the online gear store won't get you anywhere. I think the best way to do is to contact Sony, there were some info available in the PSX 2016 app I think.
