Have you ever seen the sign that says something like "No receipt given? You next drink is free. Please sms..." at all Gong Sha outlets in Singapore? Seems like this bubble tea retailer doesn't honour its word. Days and weeks past and on 16th Dec 2015 I submitted another SMS when I wasn't given a receipt again. The SMSes went unheeded. Up till today, about 2 months already, the so called "investigation" of the first case is still on going and no reply for the second case. Anyone had such similar experience?
