If you're going to book at Sussex Star make sure you use the JKQueen-Massage Wechat ID.
They also use Sussexstar888, but that seems to be the owner/mamasan (not sure who), not physically at the shop, but taking bookings on their behalf and then telling the shop. No idea why they do this; I've made bookings only to turn up at the shop and they haven't been told about my booking. Infuriating. Was then given the JKQ ID which is reception at the shop. Use that.
